The W1 stock around The Wallace Collection is Georgian and early Victorian. ONS records 88% flats, 12% houses and 3,555 households in Marylebone.
Private renting sits at 57% and owner-occupation at 32%; the first group books school clearance at short notice, the second plans it.
Expect dot-and-dab plasterboard over blockwork in W1, with metal stud partitions between rooms — the reality on the streets around The Wallace Collection behind the plaster in W1. That is why fixings are picked in the room rather than off a van shelf, and why 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 fault we are called back to undo.
Two streets can behave very differently in Marylebone: village high street, Georgian estate streets and the medical quarter along Harley Street. The quote reflects the street the job is actually on. Marylebone 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: estate-managed streets, single-yellow evening restrictions and mansion blocks with porters and small lifts. Marylebone (Bakerloo, Chiltern Railways) is the nearest station, and two to four operatives for a single-building clear, scaling to two teams working in parallel where a full primary site has to be finished inside a two-week holiday window.
