FAQ
Get answers to common questions about our garden rooms and services.
Do I need planning permission for a garden room?

Most garden rooms fall under permitted development. However, if your building exceeds 2.5m in height when within 2m of boundaries, or if you live in a conservation area, planning permission may be required.

What's included in the price?

All packages include ground screws, timber-framed base, insulation, electrics (lighting and sockets), heating system, and full installation. The Retreat and Sanctuary offer additional premium features like composite cladding or Western Red Cedar.

Are your garden rooms suitable for year-round use?

Yes. All our garden rooms feature premium insulation, weatherproof materials, and heating systems for comfortable use throughout all seasons.

What areas do you cover?

We primarily serve the West Midlands and Bristol areas from our Kidderminster base.
