Hampstead Garden Suburb is characterised by arts & crafts houses, edwardian villas, concentrated across NW11 in the Golders Green / Hampstead Garden Suburb area. The arts & crafts houses across Hampstead Garden Suburb decides how a scheme is built, not just how it looks. The Hampstead Garden Suburb version of that is simple: edwardian roofs run deeper front-to-back, so an L-shaped dormer over the back addition usually yields a second bedroom as well as the shower room. For a Hampstead Garden Suburb owner it decides the structural spec. Massing on a Hampstead Garden Suburb scheme is argued against the Central Square street rhythm.
