How It Works

We design the dormer and submit the planning application.
Bylaw Plus
Full construction drawings for the dormer structure, floor, staircase, and insulation.
Planning Note
Dormer conversions require planning permission in Jersey. Rear dormers are generally viewed more favourably than front-facing dormers by the Planning Department.
Frequently Asked Questions
Loft Conversions we have taken through planning
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.”
Roof Line Alteration
“Raising the roof ridge height to fit another bedroom seemed like a long shot. The 3D drawings provided to the planning committee showed it would not impact the street scene, and it worked.”
Velux Roof Lights
“Installing four roof lights into a sloping roof needed planning approval due to local conservation guidelines. The team handled the submission and gained approval within six weeks.”
