Where would you like to start?
Three ways into the same practice, depending on what you need first.
Planning Permission
Whether you need it, how long it takes, and what the two Jersey consents actually are.
Start here →Architectural Design
The drawings themselves — who does them, what qualifications they hold, and what you get.
Meet the team →Planning Agent
Running the application, handling the case officer, and what to do after a refusal.
See success rates →Most firms get you planning permission. We get your builder ready to start.
Standard bye-law drawings satisfy the inspector — but they leave your builder guessing on dimensions, beam sizes, and materials. Our Bylaw Plus drawings include everything: every dimension, every specification, every structural detail. The day approval lands, your builder can order materials and break ground. No second round of drawings. No delays.

Work we have taken through planning
A cross-section of Jersey projects — listed buildings, Green Zone sites, coastal plots and ordinary family extensions — in our clients' own words.
Listed Window Replacement
“Replacing the old windows on our cottage in St Ouen felt like a legal minefield. The team sorted out the historic environment details and drawings without any fuss, and the planning department approved the slimline double glazing on our first attempt.”
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.”
Loft Conversion with Dormers
“Getting dormer windows approved in a strict area was never going to be simple. These guys knew the exact guidelines to reference in our application, which saved us months of going back and forth with the department.”
Heritage Listed Building Alterations
“Dealing with historic building requirements can be tricky when you want to modernise a granite property. They produced accurate, detailed architectural plans that kept the conservation officer completely happy from day one.”
Garage Conversion
“Turned our unused double garage into a gym and extra guest room. The whole process from the initial survey to passing through the planning portal was straightforward and completely stress free.”
Farm Outbuilding Conversion
“Converting an old agricultural building into a liveable space comes with a lot of red tape in Jersey. They guided us through the change of use application smoothly and kept us updated every week.”
