Building and renovation in SW12
SW12 covers Balham, Nightingale Triangle, Hyde Farm, Heaver Estate, Bedford Hill. Substantial Victorian and Edwardian terraces on the Heaver Estate and Nightingale Triangle, Hyde Farm's uniform terraces, and conversion flats through the centre.
Planning and consent in SW12
Hyde Farm and the Heaver Estate are conservation areas with article 4 controls on windows, front boundaries and roofs. Elsewhere, generous garden depth supports large rear extensions.
Access and site logistics
Wider streets than inner London with mostly workable parking and skip permits from Wandsworth or Lambeth depending on the boundary. Many houses retain side passages for muck-away.
What we are usually asked for here
- Full-width rear and side-return kitchen extensions
- Loft conversions with bedroom, en-suite and rooflights
- Sash window and front elevation restoration under article 4
- De-conversion of flats into family houses
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.
