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.
Expect lath and plaster over timber studs in Swiss Cottage, with solid brick on the party and external walls, with 21% social-rented stock locally, block access is agreed with the estate office first behind the plaster in NW3. That is why fixings are picked in the room rather than off a van shelf, and why which crumbles the key and drops the panel — and a plasterboard plug spun into lime plaster, the reality on the streets around Swiss Cottage Library by Basil Spence is the fault we are called back to undo.
Finchley Road's shops and library beside 1930s flats and post-war blocks. That character decides the practical detail of mattress cleaning here far more than the borough boundary does. 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.
Finchley Road is a red route; loading is from side streets with permits and lift booking in the blocks. Nearest station is Swiss Cottage (Jubilee), and one technician with a portable extraction machine and air mover on a single household booking; two technicians on HMO, student accommodation and serviced-apartment rounds where six or more mattresses are cleaned in a day.
