Walk Hampstead from Hampstead Heath and Kenwood House outwards and the Georgian and early Victorian pattern is obvious: 84% of the 11,433 households in NW3 live in flats, 17% in houses.
Owner-occupation runs at 39% in Hampstead, so alongside the 45% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Walls are with solid brick on the party and external walls — and lath and plaster over timber studs — and with 45% of homes here privately rented, it sets the booking date as often as the job does, so the fixing that matters in Hampstead is chosen on site — the usual failure here is a plasterboard plug spun into lime plaster in Hampstead, which crumbles the key and drops the panel — with 17% social-rented stock locally, block access is agreed with the estate office first.
Two streets can behave very differently in Hampstead: georgian hill village of narrow lanes, artists' houses and the Heath on its doorstep. The quote reflects the street the job is actually on. Hampstead sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Steep, narrow lanes where a 3.5t Luton is the practical maximum; several streets need a shuttle from Whitestone Pond. Nearest station is Hampstead (Northern), and one fitter for doors and panels; two where a wall tunnel is core-drilled and the debris has to be carried out of a flat.
