How do conservation areas and Article 4 affect a basement under garden in Camden?

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

What Article 4 removes near Camden: Article 4 removes permitted development for HMO conversions (C3 to C4) across the borough, plus restrictions on basement extensions in 12 conservation areas. Before pricing a basement under garden we check whether the N1C address is inside the mapped area, because Camden Council draws the Camden boundary street by street rather than across the whole of Camden.

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 basement under garden 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.

The building fabric around Camden: Victorian and Edwardian terraces, Georgian townhouses in Bloomsbury and Hampstead, post-war mansion blocks, modern developments in King's Cross.

• Haringey — adjoining Camden, with 29 conservation areas centred on N4. A basement under garden on the far side of the Camden line is determined by Haringey Council, so the Camden quote for basement under gardens is checked against Haringey guidance before it is issued.
• Brent — the Brent boundary runs against Camden, so a basement under garden a street from Camden is decided by Brent Council instead. Brent runs 22 conservation areas across NW2 and its neighbours, which is why basement under gardens priced for Camden are re-checked against Brent policy whenever the Camden address sits on that edge.
• City of London — cross the Camden boundary and City of London Corporation takes the basement under garden instead, applying 27 conservation areas of its own around EC1.
