A Conversion Within Your Existing Roofline
A Velux (rooflight) conversion adds rooflight windows and usable floor space within your roof’s existing shape — no dormer, no mansard, no structural extension. It’s a genuinely different, less disruptive project than a full extension-style conversion.
Within Your Existing Roofline
Unlike dormer or mansard conversions, a Velux conversion doesn't change your roof's shape — just adds rooflight windows.
Often Permitted Development
Many Velux conversions don't need full planning permission, though this has genuine limits — conservation areas, flats, and volume allowances all apply. We confirm your situation at survey.
Warm Roof Insulation, Always
A habitable loft needs rafter insulation, not just floor insulation. We fit it as standard on every conversion.
Head-Height Matters
Available space depends on your existing roof pitch and ridge height — we assess this honestly at survey, not after work has started.
Room Outcomes We Build
A Velux conversion works well as a Home Office or Bedroom with En-Suite.
Fully Insured, Every Job
Public liability insurance covers every survey and installation we carry out.
