Stunning bespoke Sandringham garden room

Do I need planning permission?
Our standard garden rooms are designed to fall within permitted development in most cases. As a guide:
- Up to 2.5m high if within 2m of a boundary
- Further away: up to 3m, or 4m with a dual-pitched roof
- Not in front of the house, and no more than half the garden built on
- Sleeping or living in it needs planning permission
Guidance only. Check the Planning Portal or your local planning authority before you build.
Will it fit?
Talk through size, position and access with a design consultant, at your home, at a show site or by video. We can prepare a scaled drawing of your garden with the room in place.
Your questions, answered
Can't find what you need? Call 01491 612820.
Do I need planning permission for a garden room?
Typically not. All our standard garden rooms are designed to fall within permitted development, though there can be exceptions depending on where you live and where you build. Our team will advise on your situation.
Will I need a base for my garden room?
Yes. Your room sits on a concrete base, ground screws or the Crown EcoGrid base, quoted separately. An optional ground survey is available if you'd like your ground checked; it isn't needed for the Crown EcoGrid base.
Is installation included in your prices?
Yes, for customers within 100 miles of Oxford. Beyond that, a travel surcharge applies.
How long does installation take?
It depends on the collection and size. A typical medium-sized standard garden room (5m × 3.5m) takes approximately 2–3 weeks.
Are your garden rooms suitable for winter use?
Yes. Every collection is insulated and pre-wired for comfortable use through the seasons, with heating included; insulation and heating specification vary by collection (see each collection's specification).
Can you sleep in a garden room?
Only Signature garden rooms (Sandringham, Clarence and Buckingham) can be specified to Building Regulations for overnight use such as a guest room or annexe, depending on the specification and planning permission. Contemporary and Heritage are for non-habitable use (office, gym, studio, entertaining).
Where can I see a garden room?
At our show sites. Book a visit and we'll call to confirm which site has the collection you'd like to see on display.
