Census 2021 puts Belsize Park at 3,000 households with a median age of 37.8. The mainly Victorian stock is renter-heavy, which is why 7% houses and 93% flats need different handling in NW3.
Private renting sits at 51% and owner-occupation at 39%; the first group books building waste clearance at short notice, the second plans it.
Walls are lath and plaster over timber studs in NW3, with solid brick on the party and external walls — the reality on the streets around Belsize Village, so the fixing that matters in Belsize Park is chosen on site — the usual failure here is which crumbles the key and drops the panel, over a plasterboard plug spun into lime plaster — the pattern behind 3,000 households inside the NW3 neighbourhood.
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.
On access, resident-permit streets, hill gradients and conversion flats up three or four flights — one reason two crew and a Luton on most strip-outs; three crew and a tipper where the load is rubble, hardcore or soil and weight rather than volume decides the run. Fitters travelling in use Belsize Park (Northern).
