Local knowledge
What we know about building in Hampstead
Housing stock
Large Victorian and Edwardian villas, red-brick mansion blocks, Georgian terraces around the village and Arts and Crafts houses in the Garden Suburb. Many properties are listed or sit within one of Camden's conservation areas.
Planning and permitted development
Most of Hampstead is covered by conservation areas (Hampstead, Fitzjohns/Netherhall, Redington/Frognal, Belsize) and Hampstead Garden Suburb has its own Trust approval on top of Barnet planning. Rear extensions and dormers usually need full planning permission rather than permitted development, and basement proposals must meet Camden's basement policy. We handle the applications and heritage statements.

- Can I build a rear dormer loft conversion in Hampstead?
- In most Hampstead conservation areas rear dormers are acceptable where they sit below the ridge and are clad to match the roof, but they need full planning permission. Front dormers are rarely approved. We design the dormer to Camden's guidance and submit the application for you.
- Do you work on listed buildings in Hampstead?
- Yes. We have experience with listed building consent, lime plaster, sash window repair and matching historic joinery, and we work alongside heritage consultants where required.
