The Clubhouse is the most open and social of the Grandmaster range. Bi-folding French doors span the full width of the front, opening completely to connect the interior to the garden. Long opening windows on the front and sides let in natural light and ventilation. With 2m eaves height, double glazing as standard and five spacious sizes from 8×10 to 24×10, it works equally well as a garden lounge, office, bar or entertaining space.
Every Grandmaster panel is built on 27x44mm framing with key supports doubled to 54mm, giving the building a rigidity you can feel. Pressure-treated 11mm shiplap cladding with a 16mm upgrade option, an 11mm T&G roof on heavy-duty purlins and mineral felt covering as standard, backed by a 25-year anti-rot guarantee*. Built properly and treated annually, this is a building that will give you years of enjoyment.

Your Summerhouse arrives as pre-assembled, pre-insulated panels — designed to fit through a standard UK doorway and slot together with far fewer parts than a traditional log cabin. A quicker, simpler build, whether you do it yourself or bring in help.
Every building includes clear, step-by-step illustrated instructions. We recommend two people with basic DIY know-how — or add our assembly service at checkout and we'll handle it for you.
