NW7 · Mill Hill
NW7 is Mill Hill — the Mill Hill conservation area carries Article 4 directions removing permitted development across its core, so even minor external changes there need permission. Outside the designated areas, the borough's interwar semi-detached stock on generous plots keeps PD rights for many rear and loft projects.
