Decisions for SE1 are made by Southwark 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 Southwark: Yes.
Building regs from £950. We do not charge hourly. Free site survey across all SE1 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. Southwark Council timelines align with the national norm.
