Walk Swiss Cottage from Swiss Cottage Library by Basil Spence outwards and the mainly Victorian pattern is obvious: 89% of the 3,083 households in NW3 live in flats, 11% in houses.
46% of households rent privately and 33% own, which is why commercial cleaning demand here peaks around tenancy changeovers and completion dates.
Swiss Cottage substrates run to with solid brick on the party and external walls, over lath and plaster over timber studs — which is why London Borough of Camden kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in Swiss Cottage, which crumbles the key and drops the panel — measured on the walk in from Swiss Cottage (Jubilee) rather than assumed from a map is the mistake that costs a NW3 customer twice.
Two streets can behave very differently in Swiss Cottage: finchley Road's shops and library beside 1930s flats and post-war blocks. The quote reflects the street the job is actually on. Swiss Cottage 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, finchley Road is a red route; loading is from side streets with permits and lift booking in the blocks — one reason one to four operatives depending on floor area, with a named supervisor and a mobile cover team for sickness. Fitters travelling in use Swiss Cottage (Jubilee).
