The Shire Haddon Summerhouse is made from tongue and groove boards and comes delivered in full panels for ease of installation. The roof is made from a solid sheet OSB and the building kit comes complete with mineralized felt to cover the roof. The doors are half-glazed to match the surrounding walls and allow in the most of the available sunlight, even with the doors fully opened. All necessary fixtures and fittings come with the delivery, as does a full set of instructions.
