Heath-Edge Basements Are Not Village Digs
A dig beside Hampstead Heath is a slope, tree and dual-borough project. Treat it like a flat village rear extension and the package fails early.

Landscape management is not the householder LPA
Hampstead Heath is managed as landscape by the City of London Corporation. The residential planning authority for a nearby house is still the borough on the title plan — often Camden, sometimes Barnet. Mixing those audiences is how location plans and spoil assumptions go wrong.
Our Hampstead Heath basements page and basement evidence guide keep landscape sensitivity separate from householder consent.
Contour-true temporary works
On Heath-edge slopes a basement is often a stepped lower-ground against retaining ground, not a flat London box. Root protection and access for concrete on steep lanes are feasibility gates before BIA fees. Do not paste a Hampstead Village closet-wing package onto a Heath-edge dig.
Sequence that protects fees
Dual-borough check → trees → slope levels → freehold subsoil → lightwell → structure and local evidence. Technical drawings freeze only when retaining walls will not move.
