Pressure Treated Summerhouses

Our pressure treated summer houses are the perfect choice for quite literally any garden and it’s all thanks to the fantastic pressure treating process involved. Pressure treating ensures the preservative applied is done so in a uniform fashion and permeates the materials much deeper than regular surface treatment. This means your pressure treated summer house will stay preserved and protected for much longer and with our amazing prices, makes it even more of an investment for your outdoor space. With a 30 day returns policy, free delivery on selected postcodes and our professional assembly service should you need it, there’s never been a better time to grab a summer house from Project Timber. Available in a variety of styles and sizes, we guarantee to have something on offer to catch your eye and complete your outdoor space. For more information on our pressure treated summer houses, from price to installation, simply contact our friendly team today.
