Across Willesden, Harlesden, Kensal Green, Park Royal fringe, Willesden Green in NW10, the dominant property is victorian and edwardian terraces, inter-war semis and substantial industrial-to-residential conversions across willesden, harlesden and kensal green. That stock shapes what building regulations drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Brent Council judges each on design quality and neighbour impact.
