Walk St James's from St James's Palace outwards and the mixed-era pattern is obvious: 95% of the 3,927 households in SW1 live in flats, 5% in houses.
Private renting sits at 44% and owner-occupation at 28%; the first group books gym equipment assembly at short notice, the second plans it.
Walls are dot-and-dab plasterboard over blockwork; locally that also means with metal stud partitions between rooms — a median age of 35 in this neighbourhood shapes what gets ordered here, so the fixing that matters in St James's is chosen on site — the usual failure here is 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.
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.
Royal Parks restrictions, listed building rules and narrow service entrances off Duke Street. Nearest station is Green Park (Piccadilly, Victoria, Jubilee), and one fitter for bikes, benches and rowers; two for treadmills, racks and multi-gyms, or wherever the machine must be carried above the ground floor.
