20 x 8 Summerhouses

Welcome to Project Timber, home of the summer house. With over 50 years within the industry, it’s safe to say we know a thing or two about wooden garden buildings which is no doubt why we’ve become the go-to company for all things ‘garden’. When it comes to outdoor space, there’s nothing quite like creating that extra living area and our 20 x 8 summer houses are the perfect way to do that.

Our 20 x 8 summer houses are quality made inside and out. Not only do they look amazing, but they perform amazing too thanks to a fabulous anti-rot treatment and the fact that we use only the best materials and craftsmanship around. With finance available, as well as a super friendly team on hand to answer any and all of your questions, there’s never been a better reason to shop with Project Timber. Contact us today for more information on our free delivery and professional assembly service.
