Permitted development advice in Hampstead is a legal envelope check, not a style conversation. We start with designation, Article 4, listing, tenure and planning history — not with a national rear-depth diagram copied from a blog.
Camden’s Hampstead Conservation Area and street-level Article 4 regimes can remove rights that still exist a few streets away. The pin is the product. Two neighbouring houses can have different remaining envelopes after previous works.
Flats and maisonettes do not get householder extension PD. Converted houses around the village often need freeholder and planning routes instead. We say that on day one so fees are not spent drawing a PD rear that the tenure cannot carry.
Even where PD survives for an unrestricted house, we usually recommend a lawful development certificate so sale and refinance do not depend on informal assumptions. Certificate drawings must prove every condition with accurate existing and proposed geometry.
Larger-home rear extensions may need prior approval neighbour consultation — a third path between pure PD and full householder applications. We name that path when it applies rather than collapsing everything into “PD or not”.
Building regulations still apply to most PD works. “No planning” is never “no technical package”. Structure, fire, insulation and drainage remain required for meaningful projects.
This page owns rights mapping and LDC strategy. Built form pages — rear extensions, dormer lofts, wraparounds — own massing design once the route is chosen. We will not paste rear massing copy into a PD advice page.
Compared with Highgate PD reviews, Hampstead more often stays single-borough Camden with dense conservation and Article 4 grain. Compared with West Hampstead, Village and Heath-edge streets more often remove rights that patchier NW6 coverage might leave open.

A useful first pack is the address, any previous decision notices, and a sketch of what you want to build. We will map rights before selling a form.
Delivery sequence: designations and tenure → planning history → remaining envelope → pure PD, prior approval or householder pivot → LDC drawings if PD is real → building regulations for the works.
Clients who arrive with a national size table get a pin-specific rights map. That map is the product of this page; the built form is a later owner once the route is honest.
