What local planning policy applies to a kitchen extension in Camden?

Camden conservation designations: there are 40 across Camden Council, Bloomsbury, Camden Town, Fitzrovia among them. Designation costs a Camden owner the permitted-development route: a kitchen extension then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Bloomsbury is the Camden designation that most often changes a kitchen extension design.

Article 4 and your Camden kitchen extension: Article 4 removes permitted development for HMO conversions (C3 to C4) across the borough, plus restrictions on basement extensions in 12 conservation areas. At a N1C address that matters twice over, because Camden Council applies the direction unevenly across Camden — we read the Camden policies map for the exact N1C address before quoting kitchen extensions.

Camden below-ground policy: Camden's basement policy (Policy A5) restricts single-storey basements to 50% of garden area; double-storey basements generally refused outside commercial zones. Any kitchen extension in Camden that goes below existing foundations triggers two months notice under section 6 of the Party Wall etc. Act 1996, and Camden Council will want the N1C ground and groundwater position set out.
