In Swiss Cottage (NW3) the split is 89% flats to 11% houses over 3,083 households, and the stock is mainly Victorian.
Because 46% of Swiss Cottage is privately rented and 21% socially rented, a lot of NW3 work is agreed with a landlord or managing agent rather than the person opening the door.
Swiss Cottage substrates run to lath and plaster over timber studs in NW3, with solid brick on the party and external walls, measured on the walk in from Swiss Cottage (Jubilee) rather than assumed from a map. 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, where 33% owner-occupation means the same home is booked again rather than a new tenant each year is the mistake that costs a NW3 customer twice.
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. What shapes the job more is the neighbourhood itself — finchley Road's shops and library beside 1930s flats and post-war blocks — which is why a NW3 quote is not a Camden average.
Getting to the door matters as much as the job: finchley Road is a red route; loading is from side streets with permits and lift booking in the blocks. Swiss Cottage (Jubilee) is the nearest station, and two crew and a Luton for a studio or one-bed; three crew and a second van on two- and three-bedroom apartments or any duplex.
