The Different Costs of Building an Extension | Rules & Regulations
At English Heritage Buildings, we specialise in building a range of extensions for people looking to add value and space onto their property. From small carport and garage extensions to offices, home extensions and swimming pool complexes, our team has over 30 years’ experience in the oak construction industry and know the ins and outs of how much it costs to build any extension.
We will be looking at the prices of different extensions to help give you an approximation regarding your home extensions. Please remember that the below prices are approximations; all extensions we design and build are bespoke.
Standard small home extensions
Price: £10,000 – £18,000
Most small extensions cost between £10-18k depending on a variety of elements, such as the type of wood used, labour costs, and any special additions (glazing, insulation, underfloor heating etc).
Medium extensions
Price: £18,000 – £25,000
Basic medium extensions can cost anywhere between the above and again, factor in building materials, labour, and special additions. Medium extensions could be used for medium-sized offices, workshops or home gyms.
Large basic extensions
Price £38,000 – £52,000
Large basic extensions, again, use – these extensions are great for large workshops, hot tub/swimming pool areas or even office complexes for up to 15 employees.
Top-end home extensions
Top end home extensions are usually far more expensive and are built with the finest timber, glazing, decorative elements and come built-in with special additions such as:
- Underfloor heating
- Double glazing
- Bespoke designs
- Custom insulation
Top-end extensions are something we specialise in at English Heritage Buildings. We can customise your premium extension to fit your every requirement. Whether you’re looking for a stunning second living room or games room, a pool house, a grand art studio, a home gym and yoga room, or even an annex.
How long do home extensions take to complete?
This depends on a variety of factors including:
- The size of your extension
- The materials you’re building with (timber is usually faster to build with as opposed to concrete, brick cement etc)
- Your budget
- The type of extension (garage, pool house, office, gym etc)
- And any special additions you want included
Building the extension can take anywhere between two to four months depending on the size and scale of the project. Additions may also be required further down the line which could add time to the project; for example, underfloor heating or electrical appliances. Delays are to be expected so be sure that you are comfortable with the project overrunning by a few weeks or even a month. Changes to weather, hold-ups getting materials and the availability of your chosen contractors can all factor into the completion time.
Securing Planning Permission
Planning permission is also something you will need to take into consideration. However, with English Heritage Buildings, if you’re unsure whether you will be granted planning permission, this is something we can help with. We have a 99% success record of getting planning permission accepted for all extensions we take on.
