A Beginner’s Guide to Maintaining a Wooden Garden Room This Summer


Practical, versatile, and stylish, it’s easy to understand why wooden garden rooms have become immensely popular in the UK over the last few years. These stunning buildings for outdoor spaces have proved they can be used for almost anything, from home offices and living areas to workshops, art studios, and more. 

But, if you want to get year-round use from your own garden room, you have to do some work to maintain it. This includes during the summer, when you might feel like it doesn’t need touching.
As experts in the creation of precision-crafted oak frame garden rooms, we know exactly what needs to be done to keep one in its best condition. Explore our beginners’ guide to maintaining every part of your garden room this summer below, or start browsing our selection of ready-made designs.

Inspecting and Cleaning the Exterior

A clean and well-maintained exterior is crucial for the longevity and appeal of your garden room. You should start by inspecting it for any signs of damage, such as cracks, rot, or pest infestations. Addressing these issues promptly can prevent further deterioration. 

Make sure you’re using appropriate methods and products for each surface when cleaning. This includes the roof, walls, windows, and doors. Regular cleaning not only enhances aesthetic appeal but also ensures proper functionality by keeping dirt at bay. If your design has gutters, you should ensure these are emptied of leaves and other debris as well to prevent flooding later.

Inspecting and Cleaning the Interior

Cleaning and maintaining the interior of your garden room is equally important for a comfortable and enjoyable space. You should start by dusting and vacuuming regularly to remove any dirt or debris. Pay attention to areas that often accumulate dust, such as corners, shelves, and furniture. Wipe down surfaces, including windows, countertops, and furniture, using the appropriate cleaning products. 

For wooden surfaces, you might consider using a gentle wood cleaner to help maintain their natural beauty. It will also ensure they continue to complement the timeless appeal of your timber exterior. Additionally, check for any signs of moisture or humidity and take steps to address them promptly to prevent mould or mildew from forming.

Insulated Garden Rooms

Having a fully insulated garden room can help prevent the growth of mould or mildew. Insulation plays a crucial role in regulating temperature and moisture levels inside a space. It creates a more stable and controlled environment, minimising condensation and excess moisture. 

When you decide to build your garden room with us, having it insulated to make it weather-resistant is part of the standard design. This will help your space to remain long-lasting and won’t detract from the traditional appeal you’re aiming for.

Insulation also helps to improve ventilation and airflow, allowing for better air circulation and reducing the chances of dampness. We’ll talk about this more in the section below.

Maintaining Ventilation and Airflow

Proper ventilation is crucial for maintaining a comfortable environment and preventing overheating in your garden room. Good airflow helps to regulate temperature and reduce humidity levels. Consider the different ventilation options you’ve got available, such as windows, vents, or fans, to maximise air circulation. This is especially important in the height of summer, when you’re likely to be using your garden room and want to keep cool.

Opening windows strategically can create cross ventilation, allowing fresh air to flow through the space.  You can also open windows and doors on opposite sides of your room to encourage a refreshing breeze to pass through.

Managing Sunlight and Shade

Controlling sunlight in your garden room is essential. Excessive sun can cause discomfort and fade your furniture.

To manage sunlight effectively, consider installing blinds, curtains, or shades that allow you to control the amount of sunlight entering the space. These window treatments not only provide privacy, but also help regulate the temperature, protect you and your loved ones from becoming burned, and mean your furniture won’t be exposed to harmful UV rays. 

Additionally, external shading solutions like awnings or pergolas can be utilised to minimise direct sunlight exposure. This creates a comfortable, shaded area outside your garden room as well.

Preserving the Wood and Finishes

Regular maintenance is crucial for preserving the condition of your wooden garden room in the face of weathering and deterioration. To keep your surfaces top-quality, clean them regularly using gentle cleaning solutions and a soft brush or cloth. You can also apply protective coatings or stains to create a barrier that prevents sun damage and moisture absorption. 

All English Heritage Buildings garden rooms come pre-treated for your convenience. As such, you shouldn’t have to worry about this step too much for a long time to come if you’ve decided on a beautiful bespoke garden room from us. 


The surrounding landscape plays a significant role in the maintenance and appearance of your garden room. Regular landscaping tasks are essential to ensure its longevity and aesthetic appeal. Trim trees and shrubs to prevent overgrowth and potential damage to your structure. You can also clear debris, such as fallen leaves or branches, to maintain a clean environment. 

Proper drainage is crucial if you want to prevent water pooling, which can lead to moisture-related issues. When selecting plants, choose those that complement the garden room’s style but also require minimal maintenance, such as drought-tolerant varieties. By maintaining the surrounding landscape, you can enhance the beauty of your garden room as a whole.

Preserving the Charm of Your Wooden Garden Room

Ensuring the longevity and appeal of your wooden garden room is straightforward with these key strategies. 

Regular inspection and cleaning of the exterior, coupled with prompt attention to any damages, is crucial. Ensuring good ventilation aids in maintaining a pleasant atmosphere while proper sunlight and shade management helps control indoor temperature and safeguard your furnishings. And with regular upkeep of the wood and finishes, and attention to the surrounding landscape, you’ll not only enhance your garden room’s overall appeal but also avert potential issues. 

With these proactive measures, your garden room remains an inviting outdoor haven for relaxation and leisure.

What Do You Need to Know About Oak?

oak timber planks

Traditional oak framing has been a popular building system for centuries because of the many benefits associated with using green oak. The most prominent benefit is that green oak is often freshly cut, and still contains a high level of moisture. This makes it easier to work with and shape into the desired frame.

Here are more surprising benefits of using green oak for traditional framing work:

  1. Demonstrated durability and strength: Traditional oak framing using green oak has a proven track record of durability and strength. There are many examples of oak-framed buildings that have lasted for centuries, withstanding harsh weather conditions and natural disasters like earthquakes.
  2. A proven building system: The use of green oak in traditional framing is an age-old building system. The frame is designed to withstand the natural shrinking and settling that occurs as the wood dries out, making it an ideal choice for a long-lasting, sturdy construction.
  3. Tighter joints: Green oak frames are constructed with joints designed to tighten and become stronger over time as the wood dries out. This natural process ensures a tight and secure frame that is less prone to movement over time.
  4. Eco-friendly: Green oak is an eco-friendly choice, utilising a renewable resource that requires minimal processing.

Green Oak vs. Kiln and Air-Dried Oak

Air-dried or kiln-dried oak may be easier to work with initially, but neither of these offers the same benefits as green oak. Drying oak in a kiln speeds up the drying process and can result in a weaker and less durable frame. Air-dried oak, on the other hand, may take longer to dry but can still lack the benefits of green oak in terms of tight joints and proven durability.

So, traditional oak framing using green oak is a proven building system that offers durability, strength, and tighter joints. Its long history of demonstrated durability makes it an eminently reliable choice for a sustainable and long-lasting building.

Drying Oak

Drying oak beams of structural size involves removing moisture from the wood to reduce its weight. This, in turn, prevents warping or cracking and increases overall strength. The correct length of time for drying oak beams depends on the cross-section size, initial moisture content, and drying conditions.

In general, air drying is the most common method for drying oak beams. The beams are stacked with spacers between them to allow air circulation and are left in a dry, well-ventilated area where they will be protected from direct sunlight and rain.

To give an example of this, oak beams with a cross-section size of 8×8 inches can take about 1 year per inch of thickness to air-dry properly. So, a 10-inch thick beam would take about 10 years to dry completely. However, if the initial moisture content is high, the drying time may increase.

Here are a few examples of different oak beam cross-sections and their estimated air-drying times in the right conditions:

  1. 6×6 inches: about 6-8 months per inch of thickness
  2. 10×10 inches: about 1-2 years per inch of thickness
  3. 12×12 inches: about 2-3 years per inch of thickness

It is important to note that these are only rough guidelines, and the actual drying time may vary depending on the specific conditions and characteristics of the wood. To ensure that the oak beams are properly dried, use a moisture meter to monitor the moisture content and adjust the drying time accordingly.

It is also important to note that not every oak frame manufacturer will be air drying their oak correctly, or for the right length of time. Some may not be allowing sufficient time for the timber to dry fully, or may even be using substandard timber that has not been properly prepared for air drying.

Oak Timber Grades

When considering purchasing an oak frame building, it’s important to understand the different grades of oak available. Structural engineers specify the oak grade based on factors like wind loadings, orientation, and elevation, to ensure that the oak frame meets the necessary strength requirements.

At English Heritage Buildings, our oak frames are made using a higher grade than the general industry standard, and we have fully-qualified timber graders who ensure that the oak we use meets the structural engineer’s specifications.

There are different grades of oak available, such as QPA and QP1. These grades belong to the appearance class EN957-1, which is used by structural engineers to specify the strength class of the oak. These strength classes are further defined in EN 338.

When ordering from Europe, QP1 constitutes sawn timber with:

  • Practically sharp arrises
  • Fully or partially intergrown sound knots, permitted if the diameter is less than half the face width
  • Two dead knots, permitted per linear metre if less than one-quarter face width

QPA is sawn timber with:

  • Sharp arrises
  • Sound sapwood, permitted on two arrises if the total width is less than 15% of the face width
  • Fully or partially intergrown sound knots, permitted if the diameter is less than one-third of the face width
  • Dead knots, permitted where equivalent to two dead knots with a diameter less than 15mm per linear metre

English Heritage Buildings’ Requirements

We follow strict oak quality requirements when purchasing fresh green oak beams, including:

  • Sawn timber with sharp edges
  • Tolerance of small quantities of sound sapwood on two edges maximum
  • Sound knots are accepted if the diameter is below 50% of the total width
  • Grain angle not exceeding 1 in 4

Our regulated packing requirements include identifying packs by customer name and order number, and allocating an identifying colour to each supplier, which needs to be placed at the end of each beam.

In essence, we pride ourselves on employing a superior grade of oak that surpasses the prevailing industry standard. Our team of highly skilled timber graders only select oak that precisely adheres to the specifications set by structural engineers. It is crucial to comprehend the wide array of oak grades accessible and the various factors that dictate the imperative choice of grade required for your unique construction project.

How to Maintain your EHB Oak Structure

Now that you are the proud owner of an English Heritage Buildings oak frame structure,
there are a few things you will need to consider. These considerations are important for maintaining the natural beauty of your timber building.

As your frame seasons, it will gradually lose its moisture. This will result in visual changes to your frame, and the process is particularly apparent in the first few years.

Treatment of internal oak timbers can help to limit excessive movement and cracking. Internal oak timbers can be treated with a variety of products or left untreated as you wish. External oak timbers, meanwhile, can be left to weather to a silver-grey colour.

Exposure to the elements may cause oak to bleed onto the brickwork and stones. This can leave rust-like stains, but these stains will fade in time and, if desired, can be cleaned with a suitable brickwork cleaner.



The general maintenance of your weatherboard will depend on local climate conditions and the type of weatherboard that has been supplied for your frame. You should always refer to the manufacturer’s application recommendations. Follow their guidelines accordingly.

You should only need to maintain the weatherboard every 5-8 years under normal exposure conditions. However, in highly exposed locations, you can expect a need for more frequent maintenance.

Softwood Weatherboard

Your softwood weatherboard comes treated with XILIX GOLD 760 wood preservative. This water-based treatment is an effective insecticide product, working well against the wood-borer larvae of various beetle species.

Stain as soon as possible with the colour of your choice to stop water penetration and to give an even colouring. If left unstained, the timber will weather unevenly and turn a patchy grey colour in appearance. Untreated boarding will also absorb moisture, leaving the inside face of the weatherboard damp during long periods of inclement weather.

Fire-Retardant Softwood Weatherboard

Your Fire-Retardant Softwood Weatherboard comes treated with SENTRIN FRX fire-retardant chemical, necessary to meet the testing requirements of BS EN13501-01:2007 fire classification of construction products and building elements.

No further treatment is needed. If you wish to decorate, please check that the product you are planning to use is compatible for use with SENTRIN FRX Exterior. Using a non-compatible product may affect the fire-retardant properties of the weatherboarding.

Oak Weatherboard

Due to its natural properties, oak weatherboard is prone to shrinking and splitting. Unfortunately, there is no treatment that can prevent this. You may also notice a small amount of mildew forming on the faces of the board.

Oak weatherboard provides the perfect conditions for mildew spores to develop due to the moisture content, and can be more apparent during the warmer months. This is a normal feature of oak weatherboard and will disappear over time, as the oak weathers, to an attractive silver-grey.



The joinery leaves the factory having been base-coated. The base coat will protect the joinery while it is being handled prior to installation.

An important note: The base coat is not a sufficient finish. You must apply a topcoat as soon as possible.

You will need to apply your chosen topcoat to your joinery units as soon as the installation has been completed. Ensure all the edges and faces of your units are treated, paying particularly close attention to the tops and bottoms.

You should also note that once you have chosen a product to decorate your joinery, it is essential that you follow the application guidelines. Any additional coats of treatment are the customer’s responsibility.

Be aware that leaving joinery untreated may lead to cracking, splitting, or movement in the timber. English Heritage Buildings cannot be held responsible for this.

All joinery should be treated as soon as possible on both sides, top, bottom and both edges. This will prevent water stains and prevent water from being absorbed into the timber, thereby reducing the risk of problems with doors and windows and helping with maintenance and cleaning.

Prolonging the Life of Your Joinery

In order to extend the life of your joinery, you can:

Inspect the windows annually
Repair any small patches of coating damage promptly
Redecorate when the lower parts of the joinery show general signs of wear
Wash it with a solution of warm water and liquid detergent
Keep moving parts i.e., hinges, locks, handles, etc., free of grit, dirt, or mortar. Clean them regularly and apply white lithium grease for hinges and a Teflon-based dry lubricant for locks.
Do not paint over rubber gaskets or ironmongery

Gutters and Downpipes

Cleaning your gutters and downpipes regularly can increase their life expectancy, so make sure that you take the time to properly inspect and clear them.

If there are no signs of structural damage, then a thorough cleaning should be all that is required. Cleaning your gutters twice yearly, at the end of Spring, and again at the end of Autumn, will suffice.

Here are some tips on what to look out for and what to do when inspecting your gutters during the year:

  • Blocked downpipes and leaky joints during heavy rain
  • Making sure gullies at ground level are kept clean
  • Making sure vegetation is kept away from downpipes (this can be achieved by cutting it back or removing it)
  • Fitting bird or leaf guards to soil pipes and rainwater outlets to help prevent blockages
  • If your gutters are sloping the wrong way or discharging onto the wall, have them repaired

How to Clear Your Gutters

You will need to begin by cleaning any debris off your roof, using a rake or yard brush.

Using gloved hands or a small garden trowel, clear the gutters of any debris.

Flush any of the finer bits of debris down towards the downpipe using a garden hose. Ensure that water is flowing properly down the spout* when you do this.

*If you have a downpipe that is connected directly to underground drains DO NOT flush a blockage with the hosepipe.

Clearing a Blockage in Your Gutters

To clear a blockage in a downpipe you will need to take it apart, dislodge the blockage, and connect it back together.

Using a screwdriver, gently tap the downpipe where there are no blockages. You should hear a hollow sound in return. Once you have located your blockage, use a screwdriver to unscrew the downpipe clips and brackets from the wall and dismantle as much of the downpipe as necessary. Clear the pipe of the blockage and reassemble.

Remember to apply a silicone lubricant to the seals of the pieces you dismantled.

What Do We Supply?

We supply softwood carcassing cut from Douglas-fir trees. These are all grown on a specially-designated site in France, where the trees are cultivated to ensure they are as tall, strong, and straight as possible before being processed for manufacturing. This means as much of the wood is used in our work as possible and waste is minimised, as our team will carefully grade the timber for its quality before the process begins.

You can learn more about softwood carcassing timber and how it is graded by our professional timber grading team here.

Softwood Carcassing Service Life

All our softwood carcassing is supplied to C24 grade and is impregnated with Vacsol Aqua preservative using a double vacuum pressure process. This treatment gives a service life of 60 years. As with all timber treatments, if you cut and machine rafters after treatment has been done, then this affects the service life of the treatment.

We make sure that the service life is maintained by using the correct end grain treatment on all cuts before it leaves our factory. This ensures that your building has maximum protection.

What is Carcassing Timber? 

Carcassing timber is softwood that has been kiln-dried and then graded according to its strength quality of C16 or C24, before being identified with the relevant grading mark.  

Carcassing timber is often used for structural applications, such as floor joists, rafters and studwork.  

How is Timber Graded? 

The grades for carcassing timber, including C16 and C24, are set out by the British Standards Institution in the BS5258 compendium of codes. When grading the timber against these guidelines, various measurements are considered in order to assess the strength of the wood.  

Factors taken into account include: 

  • Knots 
  • Splits along the grain 
  • The slope of the grain 
  • Woodworm holes 

What is C16 and C24 Timber? 

C16 and C24 are two of the most commonly used grades of timber. The C stands for conifer, the type of tree that the timber comes from, while the 16 and 24 refer to the strength grade.  

Both grades are used in a variety of structural applications, including: 

  • Rafters 
  • Floor joists 
  • Studwork for partition walls 
  • Formwork  
  • Shuttering 
  • More beyond this

The different grades are suited to different loads.  

What is C16 Timber? 

C16 timber is one of the most popular types of timber in the UK and is utilised in a wide range of applications. These will typically be internal projects such as walls, floor, and roof joists. As well as offering strength, compression and density (qualities that are widely sought after in the construction industry), C16 timber is also usually very cost-effective.  

The reason that C16 timber is more cost-effective than other grades of timber is that it can have some defects. These include grain deviations, which can impact the strength of the timber, as well as cosmetic marks such as sap stains and uneven surfaces.  

What is C24 Timber? 

C24 timber is one of the highest quality types of timber available.  

Similar to C16 timber, it is also kiln-dried to reduce the moisture content, it typically has fewer defects, in terms of both characteristics and appearance. This makes it stronger and more resilient. It also looks better, making it a popular choice for applications that are going to be visible.  

Due to its quality, the cost of C24 timber is usually higher than C16 timber.  

What’s the Difference Between C16 and C24 Timber? 

There are several differences between C16 and C24 timber: 


Although both C16 and C24 are strong, durable, and used widely throughout the construction industry, C24 timber offers premium quality.  


C16 timber can have some defects that impact the overall appearance. C24 graded timber, on the other hand, has fewer visible defects and a more uniform appearance. This makes it the preferred choice for projects where the timber will be visible within.  


Both C16 and C24 timbers are strong enough to handle the demands of construction applications. However, C24 timber is the stronger of the two, meaning it tends to be the material of choice for larger projects or those where strength is essential.   


If you’re working to a budget, C16 timber is typically more cost-effective because it is usually produced in the UK. C24 grade, on the other hand, can only be achieved by importing the timber from areas where the climate forces a slower growth rate. This increases the cost.  

Treatment to Our Softwood Weatherboard

All our softwood weatherboard is treated with Axil 3000P, which is a water-based wood preservative.

Extra Costs to Budget for When Building a Garden Room

When budgeting for a new garden room, there is a lot more to consider than just the cost of the garden room itself. Do you require extra soundproofing? Will your garden room need electrical connections installed? How many extra windows and doors do you want, and what kind? Will you need double or triple glazing? And when it comes to building your garden room in your outdoor space, will the area need levelling or landscaping? Then, once everything is built and ready, you’ll need to consider the costs of your interior design needs.

Extra costs can also apply depending on your intended use for a garden room. If you intend to use your garden room as a home office, gym, or studio, you are free to do so at no extra cost. However, if you are planning to use your garden room as a self-contained living space, with a working kitchen and bathroom, there could be extra planning permission fees that you need to take into consideration.

If you are looking for a home extension specifically, as opposed to a traditional garden room, you can read more about the rules and regulations here, as well as our range of prices.

How to Choose the Right Garden Room Flooring

The last thing you want to do is waste time and money choosing and fitting the wrong kind of flooring for your garden room. Before you make your choice, make sure you have considered the following:

  • The intended use of your garden room: The single most important consideration is the function of your garden room. Is it a garden office or a home gym? An additional living space or a games room? Each variation requires different levels of comfort and durability.
  • The option for underfloor heating in your garden room: Most flooring materials can be fitted atop underfloor heating systems, but it is important to decide on your UFH and flooring type together, as the two work together in different ways. You could choose electric UFH which costs more to run but is better for single rooms, warm water buried UFH for its cost-effectiveness and energy-efficiency, or perhaps warm water surface-mounted UFH for a more expensive but easier-to-install system.
  • The overall budget for your garden room: Naturally, some garden room flooring is going to be more expensive than others. So consult your project budget and decide accordingly. For example, if you cannot afford natural stone or hardwood, or would prefer a more environmentally-friendly option, you can always opt for laminate as a suitable and cost-effective alternative.
  • The aesthetic of your garden room: Of course style is a factor, but one that should be thought about after the main points have been addressed. Some garden room flooring lends itself to a traditionally decorated space, with classic or heritage furnishings. Other garden room flooring is better suited to sleek and modern spaces, with minimalist design and mono-tone colour palettes. Your flooring will either enhance or detract from your overall decor – make sure it is the former.

7 Garden Room Flooring Ideas and How to Use Them

1. Hardwood Flooring

Real wood is a solid choice for most garden rooms, especially our oak frame builds. Oak, maple, and cherry are strong and durable options, ideal for garden offices and living spaces. You can opt for regular or slim wood floorboards, depending on your style, and a luxurious varnished finish. Alternatively, you can try the stripped-back look that limewashing provides, perfect for rustic or bohemian decor. Plus, with a choice rug or two, you can still add a pop of colour and personality to your space. Engineered wood is also a viable, cost-effective option made from wood fibres.


2. Stone Flooring

Though quite expensive, stone flooring is a stunning choice for garden room flooring. Stone is, of course, extremely hard-wearing, and would be perfect for both your indoor and outdoor space. In fact, stone is a brilliant way to bring some outside in and can make for a truly natural look. You can also try stone tiles if your garden room has more of a modern aesthetic, or if you would like a more unique look.

3. Marble Flooring

Similar to stone in its durability, marble flooring is a perfectly durable option for your garden room floors. Real marble floors are one of a kind in their look and come in countless colours and shades. They also work beautifully as tiles, suiting conservatory-style garden rooms best, or any garden room that is aiming for an exquisite and luxurious feel in its decor.

4. Ceramic Tile Flooring

Out of all our flooring ideas, tiles come in possibly the largest range of styles, shapes, and sizes. For real individuality and a truly timeless feel, ornate ceramic tiles are the way to go. But looks aside, they are also incredibly strong and will stand the test of time. Not only that, but they are nice and easy to clean, which is perfect for garden rooms that have a habit of attracting mud from the outdoors.

5. Laminate Flooring

For anyone looking for the look of hardwood, stone, marble, or tile flooring, but without the hefty price tag and tricky installations, laminate flooring is an ideal choice for your garden room. It is similar to vinyl flooring but comes with a host of extra benefits. Laminate flooring is made from four layers of material, consisting of melamine resin and a core of high-density wood fibre (HDF). This packed construction makes laminate very durable and moisture-resistant. Laminate flooring is also ideal for those with pets, as it is one of the most scratch-resistant surfaces on the market.

6. Rubber Flooring

In the past, rubber flooring was only available in tile form, but now a whole range of types is available, including single sheets for a seamless look. Rubber floors also come in a variety of different textures, so if you would like to improve grip or just the overall look of the flooring, you can. We would recommend rubber floors specifically for garden gyms, as they provide a hard-wearing surface that will not damage easily due to heavy equipment being dragged across it.

7. Carpet Flooring

For secondary living spaces or garden offices, carpet brings a soft and homely layer to your garden room. Though not quite as easy to clean as the materials above (make sure you have a hoover handy), carpet is unbeatable when it comes to comfort. You can create both cosy and sophisticated spaces with carpeting, as it comes in so many different types and colours. It is also simple for a professional to fit carpeting over existing hardwood flooring, which makes it ideal for when you want to change your interior design in a snap.

The 8 Best Garden Room Lighting Ideas

It is too easy to overlook lighting as an integral piece of interior design. Two lights, though both functioning the same way, will illuminate your space in entirely different ways, some better than others. When carefully chosen, the right lighting will enhance your garden room’s decor and evoke an intentional and specific mood in the space. 

Things to Consider When Lighting Your Garden Room

Before you start shopping for new lights, it is important to consider three important things first:

  • The intended purpose of your garden room: How you light your garden room will depend entirely on how you plan to use it. A garden bar favours ambience and low light whereas the same cannot be said for a garden office or gym, where ample lighting is vital. 
  • Natural light sources in your garden room: Consider the position of your garden room in relation to the sun – where and when does natural light come in? Your choice of lights should balance with the light already present in the room – if the space has more of one then lessen the other, and vice versa. 
  • Access to electricity in your garden room: It seems obvious, but electrical supply is an important consideration and will affect the lights you can and cannot include in your garden room. But if your garden room is not wired, you can always rely on battery-powered alternatives.

8 Garden Room Lighting Ideas and How to Use Them


1. Let in That Natural Light

Before you start rigging your space with an elaborate lighting scheme, it is important to remember your existing light sources – be that from windows or skylights. From there, you can decide how much additional lighting you need in your interiors. The last thing you want to do is waste time and money on daytime lighting when your windows/skylights are already pulling most of the weight themselves.

2. Flexibility is King

When it comes to lighting your garden room, flexibility is crucial. Garden rooms are versatile spaces that can change function easily, from a second living room to a garden office. So wireless or portable lighting is a fantastic way to make future change-ups easy. You can opt for floor lamps to move around the room as needed or, especially for garden offices, table lamps for handy task lighting in a pinch.


3. Vaulted Ceilings, Vaulted Expectations

Most of our garden rooms are single-storey, so often feature beautiful oak beams – however, this stunning feature can make flush-mount ceiling fixtures almost impossible to use. Instead, pendant lighting is the way to go, especially if you want to make the most of your vaulted ceiling. Alternatively, for smaller builds, you can exaggerate the height of your garden room using wall lights, specifically washers. Their light spread will give the illusion of grandiose high ceilings in a smaller space.

4. Set the Mood With Ambient Lighting

When you are using your garden room as a yoga studio or garden cinema, ambient lighting is extremely important. Track lighting can provide directional adjustability, so you can light your space easily and precisely. When creating the perfect ambient space, if you remember to do one thing, let it be installing a dimmer switch – you simply cannot beat the versatility and control that one provides.


5. Harness Solar Power

For garden rooms that lack an electrical supply, you can still light your space beautifully with solar-powered lights. For interiors, you can wire a solar panel from your roof or garden back into your garden room. This can be fiddly, but when done right the effect is seamless. Exterior solar-powered lighting is easier to manage, as most have built-in panels. This allows you to put them anywhere you like, either on a patio or dotted throughout your garden.

6. Remember Your Outdoor Spaces

On the subject of exterior lighting, it is important not to forget it. You can have a perfectly lit garden room, but an outdoor space in the dark. Your garden room is meant to be enjoyed both on its own and alongside your garden. They work as a team. So you can utilise solar lights, as above, or illuminate your garden room’s entryway with recessed lighting or wall lights, to keep your space clear but well-lit.


7. Lighting Meets Temperature Control

Your outdoor spaces and garden room verandas could also benefit from outdoor heaters. Not only will they keep you warm in the colder months, but their heat also doubles as an atmospheric light. On the contrary, for your warmer months, you could install ceiling fans that can double as semi-flush light fixtures. Whether you need warming or cooling, stay bright all year round.

8. The Cherry on Top

Once you have your practical task lighting in place, you can afford to play around a bit with additional lighting. Decorative lighting can really add a flair of personality to your garden room. From ornate light fixtures, wall sconces, and chandeliers, to beautiful and versatile fairy lights to string across your rafters or walls. Most lights can be fitted with coloured bulbs too, or even colour-changing bulbs, allowing you to set the ideal mood at any time.


Light Up Your Garden Room Today

Lights are often treated as a finishing touch, but they are so much more vital than that. Choosing the right lighting scheme for your interiors, as well as your exteriors, is crucial – and means the difference between a garden room that works and one that does not. But there is no reason for it to be difficult. We hope our ideas have helped you to make the right choice and to see your garden room ‘in a new light’.

Our Pick of the Best Garden Room Furniture Ideas

A garden room is one of the most versatile spaces on your entire property. They can function as anything from a home office to a yoga studio – and the difference lies in the choice of furnishings and decoration. But what do you choose? What is the best interior design route to take?

To answer those questions, we’ve put together this useful guide. At English Heritage Buildings, we are experts in designing and building quality exteriors for your home and garden, but we also know just how to furnish them.

10 Garden Rooms and How to Furnish Them

1. Family Room

Is your garden room a meeting spot for friends and family? A second living room of sorts, or maybe a cinema room for special nights in? Well, comfortable seating is a must for any family garden room. Set two sofas opposite each other, or perhaps one sofa with two armchairs on either side. Set a coffee table in the centre of the room for snacks and drinks storage, and either set the television on a stand or mount it within view of your seating area. Then install some heavy-duty curtains or, better yet, black-out blinds – to make the perfect den for filmgoers.

2. Garden Bar

Perhaps you want to set up your garden room as a place to spend nights with friends over a bottle (or two). A garden room can make the perfect bar, ideal for a winter’s night on the rocks or a summer’s day with a twist of lime. A well-stocked bar is the most important piece, along with a few stools so drinks can be enjoyed at the bar itself. Then, in another corner, make a more intimate space with a sofa and two armchairs – opt for velvets and gold fixtures for a warm and luxurious feel. Finally, lighting. Try a couple of floor/table lamps with dimmable bulbs and a cluster of candles on the drinks table.

We have an article dedicated to garden bars, full of alternative interior design options for your Friday night space.

3. Games Room

A games room is a brilliant way to use your garden room and make some lasting memories with loved ones. In terms of interior design, you can adapt the family room setup to accommodate an indoor game focussed space. Foldaway tables are a fantastic space saver that can be pulled out when the coffee table is too small. 

Keep the television where it is, as that could be set up as a hub for your games consoles if you have any. We would also recommend adding ample storage for the many board games and video games you will soon have in your arsenal, ready to whip out at a moment’s notice.
Check out our article on garden games rooms for a more detailed look at how to set up the perfect rainy day getaway.


4. Garden Office

Garden offices are a must for anyone looking to enhance their work-from-home experience. They grant you the vital distance between life and work, and allow you to close the door to your job at the end of the day. Every office needs a spacious desk, fitted with your chosen laptop or monitor setup, and a cupboard or filing cabinet will keep your papers together. 

Invest in a good office chair, for optimal comfort, and another chair for potential client meetings. Finally, add a ficus or monstera to add a bit of greenery and uplift the space. 

5. Quiet Study Space

For parents who homeschool, older students, or even seasoned academics, a dedicated study space could be a lifesaver. Close the door on the bustle of homelife and grant yourself or your children a place where they can concentrate without distraction. 

Bring in a desk or two, comfortable seating, a whiteboard or corkboard to aid in mental organisation, and last but not least, you need bookshelves. No study space would be complete without literature. Line your shelves with fiction or textbooks, depending on the field of study, and even purchase a book trolley for roll-around access.

6. Garden Conservatory

When a conventional conservatory extension is not possible, or not preferred, you can design your garden room to act as the perfect alternative. We offer wrap-around windows to let in plenty of natural light, and gorgeous french doors to complete the look. 

Next, depending on your style, source some wicker chairs and tables to set up alongside lots (and lots) of plants. A plant table or potting station is a great feature for practical use and storage. Then simply mix and match your chosen flora and foliage. Now you have your very own solarium, as well as a place to store your gardening supplies.

7. Music Studio

The most important part of any music studio is, ironically, silence. How better to achieve absolute silence than away from your home? Our garden rooms can be made bespoke, to include or exclude windows, and we also offer full insulation. 

After that, it will be up to you to properly soundproof your music studio with foam and acoustic panels. Then set up a desk with your computer, and perhaps a pull-out section for a keyboard. Mount a few choice guitars on the walls and perhaps your favourite vinyl framed for inspiration. Lastly, do not forget to add a seating area for comfortable listening – an L-shaped sofa would be perfect.

8. Art Studio

Sometimes you need a secluded place to make art, and space to really explore an idea – and our garden rooms are perfect for just that. So set up your easel and canvases and utilise some sets of drawers for your supplies. You could include some foldaway chairs if your garden room is large enough to house craft days with friends. And if your garden room is a permitted development, you may have plumbing facilities to make cleaning up hands and brushes at the end of the day much easier.
For more information on the status of your garden room, see our guide to obtaining planning permission.

9. Yoga Studio

Whether you like to unwind with yoga or pilates, a zen studio space is essential. You may already have your mats in hand, but you can improve the ambience with the right additions. Purchase an essential oil diffuser as a safe way to enjoy scents without heat. Then install a speaker system or tabletop Sonos so you can really get into the zone with the right playlist. Finish the space off with some floor-length mirrors, to check your posture, and a pot plant or two to enliven the space.


10. Garden Gym

A gym in your garden will save you money on expensive memberships and make it easier to maintain an exercise routine. The interior decoration for your garden gym will be quite similar to that of the yoga studio, only you will want to focus more on getting in essential equipment and weights. Keep your chosen music system in place, but opt for higher-energy tracks. Lastly, and the most important thing, is correct flooring. 

Depending on how your garden room is already floored, you may want to add some rubber mats to protect any hardwood from scratches and dents caused by heavy equipment.

How to Build a Garden Room From EHB: 5 Simple Steps

  1. It all begins with a quote. So the first thing you need to do is give us a call or request a bespoke quote. From there, you will get the chance to discuss your plans and desires with an advisor, who will be able to guide you as you decide on important details. Which frame type would you prefer? Do you want insulation? Do you have specific design requests for windows and doors? Among other crucial factors that should be straightened out before the manufacturing process can begin.
  1. Once our team has received your final designs, we will get to work manufacturing the oak timber frame for your garden room. All of our wood is graded and precisely cut using top-of-the-line machinery.

  1. Once the timber has been cut, our graders will inspect it again – checking for any signs of minor imperfections so that we can re-source fresh materials and re-cut the flawed pieces. The moment we are happy with the quality of your timber frame, we will deliver it. We ship nationwide, and you should expect to see your kit, from sign-off to arrival, within 4 to 8 weeks.
  1. Once all materials have arrived, our team of experienced professionals will get to work assembling your new garden room. This could take several weeks to a month, depending on the design specifications of your build, scheduling considerations, and preparation of your chosen terrain. We select trusted companies from across your local area to build your garden room.
  1. Once all the build is complete, and we have signed off on quality and safety checks, you will be free to enjoy your new garden room in whatever way you like.

How to Build a Garden Room Yourself

For experienced carpenters and others with construction know-how, building a garden room yourself is certainly possible. You will be responsible for sourcing and cutting your own timber and fixtures, purchasing all essential equipment, and then will come the task of laying proper foundations with concrete blocks, installing insulation and mesh, and building up the frame piece by piece.
It is an incredibly rewarding endeavour, especially once you have plastered the walls, sorted your electronics, and added finish to your floors. You can step back and behold your own creation, and hopefully enjoy it for years to come. If you need a more detailed explanation, we have a step-by-step guide on building a garden room from scratch.

Will Your Garden Room Need Planning Permission?

Whether your garden room is with our help or without, it is likely that you will not need any planning permission or building regulations before you can start work. However, this depends on how you are planning to use your garden room, and the exact specifications of the design itself. 

If you are unsure if your garden room will need planning permission or building regulations before work can start, we recommend reading our guide to planning permission. Remember, you can contact us any time, and our advisors can help you through the process of obtaining permission for your new garden room.
