Do You Need Planning Permission?
Most garden rooms fall under permitted development rights and don’t need full planning permission, provided they meet height, size and positioning rules relative to your boundary. Building Regulations may apply depending on the size and intended use, particularly if it includes plumbing or is used as habitable living space. We’ll assess your garden at the free survey stage and tell you exactly what’s needed for your project.
FREQUENTLY ASKED QUESTIONS
How long does a garden room take to build?
Most garden rooms take 4 to 8 weeks from start to finish, depending on size and specification. We’ll give you a clear timeline before work begins.
Will it be warm enough to use in winter?
Yes — we build with proper insulation in the floor, walls and roof, plus electric heating where needed, so the room is comfortable to use all year, not just in summer.
Do I need planning permission for a garden room?
Most garden rooms don’t need planning permission if they meet permitted development rules, though this depends on your garden size, boundary proximity, and the room’s height. We’ll confirm this for your specific property at the survey stage.
How much does a garden room cost?
Cost depends on the size, insulation specification, and any electrics or plumbing included. We provide a detailed, no-obligation quote after a free site survey, so you know exactly what you’re paying for before committing.
