Glevum Garden Room

Glevum Garden Room

The Glevum garden room is a striking model in our range, featuring an apex roof with a maximum exterior height of 3 metres. This allows more internal room, while still achieving height requirements for permitted development if the room is located 2 metres from boundaries.

With glazing off set to one corner, this self-build room is efficient in the use of space, offering a versatile and stylish insulated garden room for year-round use.

Cladding Options

Our Installed Garden Rooms and all of our Complete Kits offer you a choice of external cladding from either Thermowood, British Cedar, Western Red Cedar or composite. Prices are shown for each option on our models pages and assume all four walls of the building are clad in one timber type.

You can choose whether all sides of your room are clad in the same timber; where external walls are not visible you may prefer to opt for a less expensive timber and we can provide a price change for this on request.

Glazing Options

Shell Kit aperture: 2800mm

Installed and Complete Kits: 2800mm of either sliding patio or French doors with two glazed side panels.
