Walk Mayfair from Berkeley Square outwards and the mixed-era pattern is obvious: 88% of the 3,555 households in W1 live in flats, 12% in houses.
Private renting sits at 57% and owner-occupation at 32%; the first group books garden clearance at short notice, the second plans it.
Walls are dot-and-dab plasterboard over blockwork in W1, with metal stud partitions between rooms — the reality on the streets around Berkeley Square, so the fixing that matters in Mayfair is chosen on site — the usual failure here is in W1, short screws that grip only the board and slowly lever it off the dabs — and with 47% one-person households in Mayfair, one adult is usually the only pair of hands on site.
Two streets can behave very differently in Mayfair: grosvenor and Berkeley squares, private members' clubs and the flagship stores of Bond Street. The quote reflects the street the job is actually on. Mayfair sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Getting to the door matters as much as the job: extremely tight kerbside, mews arches under 2.1m and listed interiors needing floor and stair protection. Bond Street (Central, Jubilee, Elizabeth line) is the nearest station, and two crew and a Luton or tipper; three where everything has to be carried through a hallway.
