Description
Whether you’re looking for somewhere to entertain or a place to escape to for some peace and quiet, the Mercia 12 x 8 Corner Summerhouse with Side Shed could be the perfect fit! The wooden summerhouse is designed to maximise your space by sitting comfortably in the corner of your garden, while giving you fantastic panoramic views. Fitted with two fixed windows and double doors, all glazed with styrene, the interior is bright and airy. The doors are fitted with stylish brushed chrome effect handles and hinges, as well as a lock and key.
This stylish and functional garden building features a side shed, creating practical storage for all of your garden essentials. The walls are constructed using premium horizontal interlocking tongue and groove boards with a shiplap profile. The shiplap profile features a protective and aesthetically pleasing lip to create a strong, weatherproof panel. Complete with thick wooden framing to support the cladding internally, this building offers a rigid and long-lasting structure. Heavy-duty tongue and groove boards are used to construct the roof and floor, for a strong and hard wearing finish.
Robust fixtures and fittings are all supplied as standard, alongside our detailed instructions and manufacturer’s recommendations, to ensure a simple and stress free assembly. This building comes with a 10 year anti-rot guarantee, alongside a 12 month manufacturer’s warranty. Preservative and waterproof treatment is required to maintain your building and the anti rot guarantee. You must construct this garden building on a firm and level base.

On Delivery

They cannot deliver through your home or to unsafe areas. Please check all parts before arranging third-party installation.
