How It Works
Free consultation
We visit the property, assess planning constraints, and advise on what's achievable within Jersey planning policy.
Planning application
We produce the full planning drawing set and manage the application through to decision.
Bylaw Plus drawings
On approval, we produce construction-level drawings your builder can build from directly — no additional drawings needed.
Planning Note
Most single-storey rear extensions in Jersey require planning permission. Permitted development rights in Jersey are more restricted than in England. We confirm your planning position at the free consultation.
Frequently Asked Questions
House Extensions we have taken through planning
Rear Kitchen Extension
“We needed extra space for the family but were worried about overshadowing the plot next door. The drawings were spot on and tackled the privacy issues before the planning officers even had a chance to raise an objection.”
Green Zone Single Dwelling
“Because our property sits in the Green Zone, neighbours told us an extension was out of the question. The team put together a clever design that worked within the Island Plan rules and got it passed.”
Two-Storey Side Extension
“Our side extension was right on the boundary line. The team visited the site, measured everything down to the millimetre, and produced clear drawings that left no room for planning disputes.”
