Description
The 13’ x 9’ Mercia Premium Corner Summer House with Side Shed (3.95m x 2.8m) provides a beautiful outdoor living space and great garden storage, making it a fantastic garden building to fully utilise an unloved corner of the garden.
Made in the UK from premium 12mm shiplap tongue and groove cladding, on a 28mm frame, this garden summerhouse comes with both a 12mm tongue and groove floor and roof, ensuring outstanding strength and durability. The roof is fitted with a superior mineral felt cover to keep out the rain.
Access to the 9x9 summerhouse is gained through glazed double doors, which are fitted with stylish chrome-effect handles and hinges, plus a key-operated lock. Together with 4 large additional windows, they provide the interior with an abundance of natural light. All of these windows are made from shatterproof styrene, which is far tougher and safer than conventional glass.
The 4x9 side storage shed is accessed via its own set of double doors, featuring chrome-effect hinges and which can be secured by a pad bolt to keep tools and equipment safe (padlock not included).
This corner summerhouse is built from FSC®-certified timber, which is exclusively sourced from sustainable, well-managed forests. It is dip treated and supplied with an excellent 10-year anti-rot guarantee, as well as an additional 1-year parts guarantee. The anti-rot guarantee is dependent on the customer annually retreating the wood with a high-quality preservative and waterproof treatment.
Fixtures, fittings and clear instructions are all included for a straightforward assembly.
Delivery is free to most UK addresses.
