Census 2021 puts Chalk Farm at 3,654 households with a median age of 34.1. The mainly Victorian stock is social-housing-led, which is why 12% houses and 88% flats need different handling in NW3.
Private renting sits at 28% and owner-occupation at 25%; the first group books pre-move-in cleaning at short notice, the second plans it.
Walls are precast concrete panels and dense blockwork in NW3, often with surface conduit — the reality on the streets around The Roundhouse, so the fixing that matters in Chalk Farm is chosen on site — the usual failure here is in NW3, drilling blind into a panel with reinforcement or a buried cable behind it — measured on the walk in from Chalk Farm (Northern) rather than assumed from a map.
Two streets can behave very differently in Chalk Farm: roundhouse gigs, market overspill and terraces climbing towards Belsize. The quote reflects the street the job is actually on. Chalk Farm sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Market weekend congestion, narrow one-way streets and no off-street parking. Nearest station is Chalk Farm (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.
