How It Works
Consultation
We assess your loft space, roof structure, and available head height to confirm what type of conversion is feasible.
Application
We produce planning drawings and submit the application.
Bylaw Plus
Full construction drawings including floor joists, dormer framing (if applicable), staircase, and fire safety specification.
Planning Note
Loft conversions involving dormer windows or changes to the roof slope require planning permission in Jersey. Velux-only conversions may fall within permitted development but must be confirmed.
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.”
