The W1 stock around The Wallace Collection is Georgian and early Victorian. ONS records 88% flats, 12% houses and 3,555 households in Marylebone.
Owner-occupation runs at 32% in Marylebone, so alongside the 57% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Marylebone substrates run to dot-and-dab plasterboard over blockwork; locally that also means with metal stud partitions between rooms — and estate-managed streets, single-yellow evening restrictions and mansion blocks with porters and small lifts. Nothing is drilled until the wall has been sounded, because in W1, short screws that grip only the board and slowly lever it off the dabs — and with 47% one-person households in Marylebone, one adult is usually the only pair of hands on site is the mistake that costs a W1 customer twice.
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.
On access, estate-managed streets, single-yellow evening restrictions and mansion blocks with porters and small lifts — one reason two to three operatives for a small or mid-size unit, with access equipment booked separately for fascia and signage above ground floor level.
