Renovations in Hampstead Garden Suburb, NW11.

Building in Hampstead Garden Suburb.

Hampstead Garden Suburb is a planned Arts and Crafts suburb begun in 1907, with cottages and houses by Unwin, Parker, Lutyens and their contemporaries set on tree-lined roads around Central Square. The whole Suburb is protected twice over, by Barnet as a conservation area and by the Hampstead Garden Suburb Trust, which must approve any external change.

Owners here typically want to extend and modernise without losing what makes the houses special. That means extensions designed in the Suburb's own language, roofs and windows that follow the Trust's guidance, and interiors that bring services and kitchens up to date while keeping the original joinery and proportions.

The whole Suburb is a conservation area, with Article 4 directions on every street and the Hampstead Garden Suburb Trust as a second consenting body.
