Planning Permission for Garden Rooms in Windsor
Most garden rooms in Windsor fall under permitted development — single-storey, under 2.5m tall within 2m of a boundary, covering no more than 50% of the garden. Windsor has several conservation areas, particularly near the castle and the river, where additional restrictions may apply. The Royal Borough of Windsor and Maidenhead also has specific guidance for properties within the Windsor Conservation Area. We'll advise on this during your free consultation and can handle planning applications if needed.
