Queen's Park terraces and Wembley semis
The south-eastern corner of the borough — Queen's Park, Kensal Rise, Brondesbury, Kilburn — is late-Victorian terrace, with narrow rear gardens behind houses that have very often been extended at the back already. What is left of the garden after a full-width rear extension is frequently short and wide, which is a genuinely different design problem from the long thin plot everyone imagines. North and west of there, Wembley, Kingsbury and Neasden are inter-war semis on regular plots with side access, a driveable frontage and rear gardens with room for a lawn, a terrace and a garden building.
