Roof lights only — often the simplest planning route.
Velux loft conversion in Jersey — planning and bye-law guide.
A Velux loft conversion uses roof lights set flush into the existing roof slope rather than adding a dormer. It may fall within permitted development in Jersey, avoiding the need for a full planning application. We confirm your planning position and handle bye-law drawings.

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.”
