Dormer, hip-to-gable and Velux loft conversions that add a bedroom or office under your Balham roof.
We convert lofts for homeowners across Balham and SW12. On the typical Victorian and Edwardian terrace, a dormer or hip-to-gable conversion adds a double bedroom with an ensuite, or a quiet office, without taking any garden. We handle design, planning, building control and the build, so you deal with one team throughout.
A loft conversion is often the best value way to add a room to a Balham house, because it uses space you already have. The most common on local terraces is a rear dormer, which gives full headroom and room for a double bedroom and a small ensuite.
We take it from first design to finished room: survey, drawings, structural calculations, the planning or permitted development route, building control, and the build with our own trades, including the stairs, insulation, plastering and finishing.
Typical build: 6 to 10 weeks on site
Planning: Permitted development or full application
Adds: Bedroom, office or ensuite
Covered: Balham and SW12, plus SW4 and SW17 edges
The right type depends on your roof shape and what you want to add.
Balham's Victorian and Edwardian terraces usually convert well, most often with a rear dormer or a hip-to-gable on end terraces and semis. Mansard conversions are sometimes the better route where a conservation area limits what you can do at the rear. We check your roof and the planning position before any design work.
We check your loft, headroom and roof, then send a written quote.
We prepare drawings and calculations and handle planning or permitted development.
We build the conversion, stairs, dormer and ensuite, keeping you updated.
Building control signs it off and we hand over the finished room.
Many rear dormers and rooflight conversions fall under permitted development, but conservation areas and flats change that. We check your address and handle a full application if one is needed.
A standard dormer conversion in a Balham terrace usually takes around 6 to 10 weeks on site, depending on the design and whether you add an ensuite.
Yes. Most of the loft conversions we do include a small ensuite, which we design into the layout and plumb in as part of the build.
We add new floor joists sized by a structural engineer, so the new room is properly supported without relying on the old ceiling.
Yes. We design and build the new stairs to building regulations, working out the best position to lose the least space on the floor below.
Loft Conversions is one of ten building services we offer across Balham and SW12. If your project needs more than one, we handle them as a single job.
