We manufacture this building using premium materials to create a high quality build. The roof and floor are formed using tongue and groove boards that lock together for a robust and heavy-duty finish. The walls are constructed using 12mm Shiplap tongue and groove boards that create a tight seal against the elements and offer a strong and hard-wearing build. We provide high quality mineral felt with this summerhouse to ensure it has added protection against the weather. We supply robust fixtures and fittings with this summerhouse, including a lock and key for security. We offer a 10 year anti-rot guarantee alongside our standard 1 year manufacturer’s warranty. Provided you treat the building once installed, and again annually, with high quality timber preservative and a waterproof top coat, your guarantee will be good to go! Manufactured here in the UK, using sustainably sourced and regulated timber. Features: Enjoy our 10-Year Anti-Rot Guarantee Opt for professional home installation
