Garden Room FAQs
Garden room vs extension — which is better value?
Garden rooms typically cost 40–60% less than a brick extension per m² and avoid VAT on planning and structural work. They also don't reduce your indoor floor area or trigger a building reg upgrade to your house.
Can I sleep in a garden room?
You can sleep in one occasionally, but using it as a permanent bedroom changes its classification and may require building regulations approval and planning permission.
