Quick answer

Garage conversions in Brent are common in the 1930s and post-war semis of Wembley, Kingsbury and Kenton (HA0, HA9, NW9). Most integral garages convert under permitted development — no planning required outside conservation areas. Building regulations cover thermal (Part L), fire (Part B), ventilation and structural lintels. Typical cost £13,000–£26,000. Queen's Park and Mapesbury CA properties need planning permission if external appearance changes. Off-street parking retention is a consideration in restricted permit zones.
