FAQs

Common questions

Which areas do you cover?

We're based in Mangotsfield and cover Filton and the surrounding area, including Bradley Stoke, Patchway, Stoke Gifford, Winterbourne, Frenchay, Downend, Emersons Green, Almondsbury and Henbury. See our areas we cover page for details on each.

Do I need planning permission for a house extension?

Many single-storey extensions fall under permitted development rights, but this depends on your property, its planning history and the size and position of the extension. We'll talk through your specific situation before anything is designed.

Do you handle building regulations and building control?

Yes — we coordinate with building control throughout a project and make sure the work is signed off properly at each stage.

Can you match brickwork on an extension to the existing house?

Wherever possible, yes. We source matching brick and mortar colour to keep a new extension looking like part of the house rather than an obvious addition.

Thinking about an extension or renovation?

Give us a call or drop us an email — we'll tell you honestly what's realistic and what it'll take to get there.
