Building work we do in Forest Hill and Honor Oak
- House extensions – rear, side return and wraparound extensions for Victorian and Edwardian homes.
- Loft conversions – rear dormer, L-shaped and hip-to-gable lofts.

Building on Forest Hill and Honor Oak’s period homes
Most homes here are Victorian and Edwardian terraces and semis, many on sloping streets. They suit rear extensions and loft conversions, but they come with shared party walls, changes in ground level and, in some streets, conservation area rules. We plan for these from the start: party wall notices, structural design, site access, and planning or permitted development with Lewisham Council.
