Does Camden planning policy restrict a house extension cost single?

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 house extension cost single then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Primrose Hill is the Camden designation that most often changes a house extension cost single design.

Camden and Article 4: Article 4 removes permitted development for HMO conversions (C3 to C4) across the borough, plus restrictions on basement extensions in 12 conservation areas. A house extension cost single planned at a N1C address is checked against that direction first; Camden Council publishes the Camden extent, and the N1C line rarely follows the Camden boundary you would expect.

Digging below a Camden property: Camden's basement policy (Policy A5) restricts single-storey basements to 50% of garden area; double-storey basements generally refused outside commercial zones. Where a house extension cost single in Camden involves excavation that is read beside the Party Wall etc. Act 1996, which needs two months notice for a Camden dig within 3 m of a neighbour, and Camden Council expects the N1C ground conditions addressed in the application.

What Camden is built from: Victorian and Edwardian terraces, Georgian townhouses in Bloomsbury and Hampstead, post-war mansion blocks, modern developments in King's Cross.
