Dormer, hip-to-gable and mansard loft conversions for Brixton houses and top-floor flats.
We convert lofts across Brixton, in SW2 and SW9. On a house, a rear dormer usually gives you a double bedroom and shower room without touching the garden. A lot of Brixton’s period houses are now split into flats, and if you own the top flat the loft can often become part of it, with the freeholder’s agreement. We handle the design, planning, building control and the build.
Most of Brixton’s housing is late Victorian, and those terraces usually have enough roof height for a rear dormer. The larger houses off Brixton Hill and near Brockwell Park often suit an L-shaped dormer that runs over the back addition, giving room for a bedroom and a separate bathroom.
For a top-floor flat in a converted house, the roof space normally belongs to the freeholder, so you need their agreement and usually a lease variation before any building. Flats also need full planning permission because they have no permitted development rights. We prepare the drawings for both and run the build once the paperwork is in place.
Typical build: 8 to 10 weeks on site
Houses: Often permitted development
Top-floor flats: Planning and freeholder consent
Covered: Brixton SW2 and SW9
The roof shape, the street and who owns the roof space decide what you can build.
Brixton has several conservation areas, including Rush Common and Brixton Hill, Brixton Water Lane and Brixton Town Centre. Inside them a dormer is not permitted development, so it needs a planning application to Lambeth. A rooflight-only conversion can often still go ahead without one. We check your address first, then design for the route that fits.
Much of Brixton’s period housing was split into flats in the early twentieth century, so top-floor loft conversions are common here. We work with your freeholder or managing agent on consent, provide the drawings they need for a lease variation, and plan the build so the flats below stay protected during the works.
We look at headroom, roof structure and the planning position, then send a written quote.
Drawings, calculations, planning or a lawful development certificate, and freeholder consent for flats.
Steels, joists, dormer, stairs, insulation and the new shower room or ensuite.
Building control inspects and signs off, including fire safety for the new storey.
Outside a conservation area, a rear dormer on a house is often permitted development. Inside one, such as Rush Common and Brixton Hill or Brixton Water Lane, it needs a planning application. We check your address and handle either route.
Often, yes. You will usually need the freeholder’s consent and a lease variation to take in the roof space, plus planning permission. We supply drawings for both and build once they are agreed.
Around eight to ten weeks on site for a standard dormer, longer for a mansard or an L-shape. You get a programme with your quote.
Adding a storey means a protected escape route, usually fire doors onto the stairs and linked smoke alarms. We design this in and building control checks it before sign-off.
The new staircase takes some room. We position it over the existing stairs where we can, so you lose as little as possible.
Loft Conversions is one of ten building services we offer across Brixton, SW2 and SW9. If your project needs more than one, we run them as a single job.
