What began as restoring century-old barns across Sussex has transformed into a national oak construction company serving thousands of loyal customers across the UK, and this all began in Sussex.
With over 50 traditional garden room designs to choose from and adapt, we offer the most comprehensive timber garden room builds in Sussex and the UK. All designs are made bespoke to your needs, at prices that are fair and with no hidden additional costs.

Our team adheres and are made aware of all updates regarding social distancing rules for COVID-19. You can rest assured that your project will be handled with the utmost professionalism and safety to ensure you have never put yourself at risk. Before we install your garden room, we will need to visit your garden to perform a free site survey. Once completed, your garden rooms will then be designed, built and prepared in our Sussex workshop for safe transportation to your garden. Here, we will begin unpacking and installing your bespoke garden room, ensuring at all times weβre adhering to all COVID-19 regulations.
You can design your garden room to accommodate any need, the limit is your imagination. Maybe youβre looking for a summer house to enjoy throughout the warmer seasons that can also act as a storage unit, or you want something smaller and affordable pergola-based sitting area for enjoying your morning coffee

Home gyms are an attractive prospect for many people who enjoy exercising within the comfort of their own property, and those who are unable to attend their gym due to COVID-19.
If this is something youβre interested in, simply select one of our pre-built designs, add any additional extras youβd like to complete your home gym and send your requirements to our team. Green oak is a naturally fantastic insulator, making home gyms an appealing concept even in the colder months.
Summer houses are arguably the most popular garden room we build in Sussex. This is probably down to their versatility, as our English Heritage Building summer houses are typically built to be multifunctional. For example, in the colder months, your summer house could transform into a garden equipment/furniture storage unit or a log cabin. Alternatively, you could elect to use it as a winter cabin as our timber frames act as fantastic insulators and will help keep the building warm during the colder months.
Whichever design you choose, our team is here to provide helpful advice and support to ensure youβre getting the most out of your investment.
