NW8 primarily covers St John's Wood in Westminster. It also touches Camden.
Decisions for NW8 are made by Westminster City Council. Standard Permitted Development rules apply for most rear extensions and loft conversions on terraced and semi-detached houses, unless the property is in a conservation area, is listed, or sits under an Article 4 Direction. Article 4 in Westminster: Yes.
Building regs from £950. We do not charge hourly. Free site survey across all NW8 addresses.
From first call to planning decision: typically 12–14 weeks. Site survey week 1, design weeks 2–3, validation 1–2 weeks, statutory 8-week determination. Westminster City Council timelines align with the national norm.
St John's Wood in NW8 is characterised by the housing stock of Westminster — broadly grand georgian and regency terraces in belgravia and pimlico.
