Solid Tongue and Groove Construction

Solid Tongue and Groove Construction

Built using Tongue & Groove panels, the Lily has a secure and stable structure which is built to last. The panels interlock, creating a smooth finish which enhances the style of the summerhouse. The interlocking Tongue and Grooves form strong panels which create a strong structural strength.

All of our buildings are Spray Treated for transit, but we recommend treating the wood after installation to protect it. Paints are available in a variety of colours, so you can protect your building whilst decorating it in a way which looks great in your garden. Note; Paint is supplied in a tin for application, not pre painted.

Georgian Bar Door and Windows

The Lily has a centralised entrance, which have Georgian bar door and windows. These are are what give the summerhouse its beautiful, traditional look. If your garden does have limited space, it’s no problem as the Lily can fit into tighter spaces, or corners. The Georgian windows are glazed using a 1.2mm styrene, with the doors using a 1.8mm styrene.

The veranda also offers a great space for potting plants or hanging garden flowers, why not have your garden and summerhouse combine as one.

Range of T&G Flooring Options

The Holly summerhouse is available with different heavy-duty flooring options.

The 11mm T&G provides a stronger, interlocking floor for the shed. For larger and heavier items, we recommend, our premium flooring options which are the 19mm T&G floor and the pressure treated 19mm T&G floor.
