Loft Conversions
A loft conversion is usually the most cost-effective way to add a bedroom and bathroom to a London house. We assess your roof structure and head height at the survey, recommend the type that suits your home and handle the structural work, staircase, wiring, plumbing and finishing. Find out more about our loft conversions.
- Velux loft conversionRoof windows fitted into the existing roof slope, with no change to the roof shape. Usually the simplest and least disruptive way to use a loft with enough head height.
- Dormer loft conversionA box-shaped extension built out from the rear roof slope, giving full standing height and room for a bedroom and en-suite.
- Hip-to-gable loft conversionFor semi-detached and end-of-terrace houses with a sloping side roof: the side is built up into a vertical gable wall to create a much larger loft, often combined with a rear dormer.
- Mansard loft conversionThe rear roof slope is rebuilt almost vertically with a flat top, giving the most usable space of any loft type. Usually needs planning permission and is common on London terraces.
- L-shaped loft conversionTwo dormers joined in an L shape, one on the main roof and one over the rear outrigger. Popular on Victorian and Edwardian terraces for adding two rooms.
- Trussed roof loft conversionMany post-1960s homes have W-shaped roof trusses rather than a traditional cut roof. The roof is re-supported with steel beams designed by a structural engineer, so the loft can be opened up and used.
- Shell loft conversionWe complete the structural and weathertight work, including the dormer, steels, floor and staircase opening, and you finish the interior yourself or with your own trades.
