Dormer and Hip-to-Gable Loft Conversions in Lewisham

Crest Building Services builds loft conversions for homeowners across Lewisham and the wider Greater London area, with founder and bricklaying specialist Wayne overseeing the structural work from the first inspection onwards. Where a conversion needs new masonry, such as a gable wall for a hip-to-gable, that brickwork is carried out in-house rather than passed to a separate trade.

Based in nearby Bexleyheath, Crest Building Services covers Lewisham and the wider Greater London area, including neighbouring Lamorbey and Longlands.

What Loft Conversions in Lewisham Involves

We coordinate building regulations compliance throughout the conversion, covering fire safety such as protected escape routes, insulation standards, safe staircase access and the structural floor strengthening. This is managed alongside the build rather than left for you to organise, so the finished loft is signed off as a fully compliant habitable space, not a room that struggles under scrutiny later.

There are three main conversion types and the right one depends on your roof. Rooflight-only conversions keep the existing roof line and often fall under permitted development. Dormer conversions add headroom and floor space by building out from the roof slope. Hip-to-gable conversions replace a sloping hip end with a vertical gable wall to gain volume, and terraced and semi-detached homes across the area often suit a rear dormer or hip-to-gable particularly well.
