20 x 10 Summerhouses

Summer houses come in a variety of shapes and sizes, suitable for all types of garden designs and of course shapes and sizes. Here at Project Timber, we recognise the need for variety only too well which is why we offer summer houses in a variety of options. From our more modest 10 x 6 summer house to our much larger 20 x 10 summer house. Our 20 x 10 summer house is perfect for providing a great amount of seating for larger families (and friends for that matter) which is no doubt why it’s become so popular. Made from using only the finest materials and assembled by our professional team should you wish, buying a larger than average summer house has never been easier.

What’s more, with Project Timber, you can guarantee quality all the way with our 10 year anti-rot guarantee as well as our 30 day returns policy. For more information on our 20 x 10 summer house and how you can get your hands on one, simply contact us today.
