The NW3 stock around Belsize Village is mainly Victorian. ONS records 93% flats, 7% houses and 3,000 households in Belsize Park.
Private renting sits at 51% and owner-occupation at 39%; the first group books extractor fan cleaning at short notice, the second plans it.
Belsize Park substrates run to lath and plaster over timber studs in Belsize Park, with solid brick on the party and external walls — which is what a 93% flat share across the ONS neighbourhood covering Belsize Park actually produces. 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 — the pattern behind 3,000 households inside the NW3 neighbourhood is the mistake that costs a NW3 customer twice.
Two streets can behave very differently in Belsize Park: stucco villas and mansion blocks on the slope between Hampstead and Chalk Farm. The quote reflects the street the job is actually on. 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.
Getting to the door matters as much as the job: resident-permit streets, hill gradients and conversion flats up three or four flights. Belsize Park (Northern) is the nearest station, and one technician for domestic hoods and bathroom fans; two for island canopies and any commercial kitchen.
