Building and renovation in SW4
SW4 covers Clapham, Clapham Common, Old Town, Abbeville Village, Clapham North. Georgian houses around the Old Town, long Victorian terraces in Abbeville Village, and large conversion flats across the whole district.
Planning and consent in SW4
Clapham Common, the Old Town and Abbeville sit in Lambeth conservation areas where rear roof form, front elevations and window detail are controlled. Side-return infills are extremely well precedented.
Access and site logistics
Permit parking near the Common, with skip licences typically straightforward. Many terraces have rear garden access via neighbouring plots, which needs agreement rather than assumption.
What we are usually asked for here
- Side-return and full-width rear kitchen extensions
- Rear dormer loft conversions with bedroom and en-suite
- Flat refurbishment with acoustic separation between dwellings
- Whole-house renovation of Georgian and Victorian stock
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.

Clapham's Victorian terraces frequently have a cellar under the front room and a lightwell to the street, and dig-outs to create a full lower ground floor are common on the larger streets.
For a straightforward cellar we line with cavity drain membrane, form a drainage channel and set a single sump with a backup pump. For a dig-out with underpinning the Type C system is designed alongside the temporary works, so the drainage route is fixed before the slab is poured.
A Type C cavity drain system in SW4 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 SW4?
Damp proofing deals with moisture in above-ground walls. Waterproofing protects a room that sits below ground against water pressure from outside. In Clapham we decide which one the property needs at the survey, and often the answer is an external repair first.
How a SW4 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.

Garden designer in SW4
Clapham gardens behind Victorian terraces are often long and narrow, suiting zoned terraces, lawns, studios and screening planting.
South west London gardens behind terraced and semi-detached houses are often long and narrow, used as family spaces, with garden rooms, terraces and lighting frequently requested.
Our garden design and landscaping service covers layout, levels and drainage, planting, terraces and paths, garden lighting and external power, and how materials and plant reach the garden. In SW4 that access question matters: Permit parking near the Common, with skip licences typically straightforward. Many terraces have rear garden access via neighbouring plots, which needs agreement rather than assumption.
Garden designer London →Roofing in SW4
SW4 roofs commonly combine slate main roofs, valley gutters and rear flat roofs, often near completed loft conversions.
Typical roofs combine pitched slate or tile main roofs, rear outrigger roofs, valleys and dormers, often alongside loft work already completed or planned.
Roofing work starts with a survey and photographs, then a written scope that states whether repair or replacement is recommended: pitched and flat roofs, leadwork and flashings, guttering and rainwater goods, and the scaffolding the roof needs. Planning, conservation and freeholder requirements for your address are confirmed at survey.
