Building and renovation in SW18
SW18 covers Wandsworth, Earlsfield, Wandsworth Common, Southfields, Tonsley Estate. Victorian terraces around the Tonsley Estate and Earlsfield, larger houses facing Wandsworth Common, Southfields' Edwardian grid and riverside conversions on the Wandle.
Planning and consent in SW18
Wandsworth conservation areas cover the Tonsley streets and parts of the Common; much of Earlsfield and Southfields remains outside them, so lawful development certificates carry many rear and loft schemes.
Access and site logistics
Terraced streets with permit parking, but generally easier skip and grab access than inner London. One-way systems around the town centre govern delivery routing.
What we are usually asked for here
- Side-return and rear kitchen extensions with bifold or slim-framed glazing
- Rear dormer and mansard loft conversions
- New builds and infill housing on cleared or backland plots
- Full-house refurbishment including roofs, wiring and heating
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.

Wandsworth and Earlsfield sit on clay with a mix of Victorian terraces and newer riverside conversions. Old cellars are often partly below the garden, with the retaining wall taking water from saturated ground.
Cavity drain membrane to the retaining walls, a channel taken to a sump at the lowest corner, and a floor membrane under insulation and screed. We also correct the external causes — ground levels, gullies, downpipes — so the pump is not running continuously.
A Type C cavity drain system in SW18 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 SW18?
Damp proofing deals with moisture in above-ground walls. Waterproofing protects a room that sits below ground against water pressure from outside. In Wandsworth & Earlsfield we decide which one the property needs at the survey, and often the answer is an external repair first.
How a SW18 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 SW18
Wandsworth and Earlsfield gardens are often long terrace plots, suited to zoned family spaces, studios and lighting.
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 SW18 that access question matters: Terraced streets with permit parking, but generally easier skip and grab access than inner London. One-way systems around the town centre govern delivery routing.
Garden designer London →Roofing in SW18
SW18 roofs often combine Victorian slate, rear outriggers and loft dormers, so leadwork and junctions are surveyed carefully.
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.
