In Belsize Park (NW3) the split is 93% flats to 7% houses over 3,000 households, and the stock is mainly Victorian.
With 51% private renting against 39% owner-occupied, most NW3 bookings land on a move-in day rather than a weekend.
Belsize Park substrates run to with solid brick on the party and external walls — and lath and plaster over timber studs, and with 45% one-person households in Belsize Park, one adult is usually the only pair of hands on site. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster; locally that also means which crumbles the key and drops the panel, a median age of 38 in this neighbourhood shapes what gets ordered here is the mistake that costs a NW3 customer twice.
Belsize Park sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate. What shapes the job more is the neighbourhood itself — stucco villas and mansion blocks on the slope between Hampstead and Chalk Farm — which is why a NW3 quote is not a Camden average.
Resident-permit streets, hill gradients and conversion flats up three or four flights. Nearest station is Belsize Park (Northern), and one cleaner for a flat; two for a house, so the property is finished in one visit rather than split across a day.
