Builders in SW9
Stockwell & North Brixton · South West London
Building and renovation in SW9
SW9 covers Stockwell, North Brixton, Angell Town, Stockwell Park Crescent, Loughborough Junction fringe. Georgian and early-Victorian villas on Stockwell Park Crescent and Albert Square, mid-Victorian terraces towards Brixton, and many large period houses divided into flats with a lower ground floor unit.
Planning and consent in SW9
Stockwell Park, Albert Square and Angell Town conservation areas cover the best period streets; mansard roofs and front alterations are tightly controlled, while rear extensions are well precedented.
Access and site logistics
Controlled parking, bus-heavy Clapham Road and Brixton Road, and limited rear access to most terraces. Waste and materials go through the house, so protection and scheduling matter.
What we are usually asked for here
- Lower-ground-floor flat renovation and waterproofing
- Rear kitchen extensions and side infills
- Loft conversions and mansard schemes where consented
- De-conversion of flats back to a single house
We survey the property before pricing, confirm the constraints that apply to your specific address rather than the postcode, and issue a fixed price against a written scope. One site manager runs the trades from first fix to snagging.

Stockwell's villas and Brixton's divided houses commonly have a lower ground floor flat with a front area and vault, where failed tanking from earlier refurbishments is a frequent problem.
We strip failed tanking and salt-damaged plaster, fix cavity drain membrane to the walls and floor, run a drainage channel to a sump with duty and standby pumps, and correct the front area drainage that was feeding the damp.
A Type C cavity drain system in SW9 is specified after a survey, designed to BS 8102 for the way you intend to use the room, and installed with the drainage channel, sump and pumps left accessible for maintenance. Read the full basement waterproofing and Type C cavity drain guide, or see how it fits into a basement and cellar conversion.
Waterproofing or damp proofing in SW9?
Damp proofing deals with moisture in above-ground walls. Waterproofing protects a room that sits below ground against water pressure from outside. In Stockwell & North Brixton we decide which one the property needs at the survey, and often the answer is an external repair first.
How a SW9 quotation works
We visit, find the source of the water, check head height, drainage outfall and any lease or listed-building constraints on your address, then issue a written scope and fixed price covering membrane, channel, sump and pumps and the finished room.
