Most garden buildings fall within Permitted Development rights requiring no planning permission if they meet certain criteria: maximum 2.5m high with flat roofs (4m for pitched), no higher than existing house, and positioned away from boundaries. Larger buildings, those with sleeping accommodation, or buildings in conservation areas typically require planning permission. Building Regulations apply to buildings with sleeping accommodation or those over 30 square meters with substantial glazing. We provide expert guidance on all requirements.
