Talk It ThroughThe parts that decide whether a garden room is usable in February.
Ground screws or a concrete base set out level and to depth, so the structure does not settle, twist or take up damp from the ground.
Insulated floor, walls and roof with a membrane and ventilation detail, so the room holds heat in winter and does not run with condensation.
First and second fix electrics run back to the house by the group's own electricians, so the room works as an office from day one rather than on an extension lead.
Most garden rooms fall under permitted development, but height, position and how you intend to use it all matter. We check your specific garden before quoting.
We build across Cardiff and Caerphilly, and out to Penarth, Barry and Pontypridd. A garden room usually sits alongside other work — a patio or path up to the doors, fencing or decking around it, and the planting that makes it feel part of the garden rather than parked in it.
Wondering about permission? In Wales the limits are not England’s, and one of them decides where the building can sit: anything within 2m of the house is capped at 1.5m tall. Do I need planning permission for a garden room? sets out the height limits by roof type, the 50% garden rule, what changes in a conservation area, and the 15m² and 30m² building regulations lines.
