Quick Answers

Common questions about garden rooms

Do I need planning permission?

Most garden rooms fall under permitted development, so no planning permission is required, provided the building meets height, footprint and boundary limits. We confirm this on a free site visit.

Can it be used all year round?

Yes. Every garden room we build is fully insulated with proper foundations, electrics and glazing, so it stays comfortable in every season.

How long does it take to build?

Typical lead times are 4 to 8 weeks from base and groundwork through to cladding and electrics, depending on size and specification.

What sizes do you build?

We build bespoke garden rooms from compact 3x3m studios up to larger multi-room garden offices and annexes.
