Another extremely popular size when it comes to summer houses is 7×5. Our range of 7×5 come from Shire and Mercia. These are either dip or pressure treated to ensure that you get to enjoy your summer house for the longest time possible. In fact, there is up to a 10 year anti-rot guarantee with some of these. The dimensions make these summer houses perfect regardless of the size of your outdoor space. They can make a prominent feature of a smaller garden who can be slightly more discreet in the background if your outdoor space is bigger.
