The SW1 stock around St James's Palace is mixed-era. ONS records 95% flats, 5% houses and 3,927 households in St James's.
Private renting sits at 44% and owner-occupation at 28%; the first group books carpet fitting at short notice, the second plans it.
St James's substrates run to dot-and-dab plasterboard over blockwork in SW1, with metal stud partitions between rooms — and with 44% of homes here privately rented, it sets the booking date as often as the job does. Nothing is drilled until the wall has been sounded, because short screws that grip only the board and slowly lever it off the dabs on these streets — which is why Westminster City Council kerb rules get settled before the van is loaded is the mistake that costs a SW1 customer twice.
Two streets can behave very differently in St James's: gentlemen's clubs, galleries and Jermyn Street shirtmakers between the palace and Piccadilly. The quote reflects the street the job is actually on. St James's 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: royal Parks restrictions, listed building rules and narrow service entrances off Duke Street. Green Park (Piccadilly, Victoria, Jubilee) is the nearest station, and one fitter for a room or a straight flight; two for large open-plan floors, winder staircases and anything carried up above the third floor without a lift.
