Building work we do in Dulwich and West Norwood
- House extensions – rear, side return and wraparound extensions for period and family homes.
- Loft conversions – rear dormer, L-shaped and hip-to-gable lofts.
- Zinc and aluminium roofing – standing seam roofs for extensions and dormers, a popular finish on period homes.
- Full refurbishments – kitchens, bathrooms, rewiring, heating and complete house renovations.
Building on Dulwich and West Norwood’s homes
The area has a mix of Victorian and Edwardian terraces, larger semi-detached and detached family houses, and conservation areas around Dulwich Village and parts of West Norwood. Homes on the Dulwich Estate may also need the Estate’s consent for external alterations, in addition to planning permission. We plan for this from the start: party wall notices, structural design, site access, and planning or permitted development with Southwark Council or Lambeth Council.
Recent work nearby
