Walk Marylebone from The Wallace Collection outwards and the Georgian and early Victorian 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 house and flat clearance at short notice, the second plans it.
Marylebone substrates run to with metal stud partitions between rooms — and dot-and-dab plasterboard over blockwork — which is what a 88% flat share across the ONS neighbourhood covering Marylebone actually produces. 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 — the pattern behind 3,555 households inside the W1 neighbourhood 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.
Estate-managed streets, single-yellow evening restrictions and mansion blocks with porters and small lifts. Nearest station is Marylebone (Bakerloo, Chiltern Railways), and a two-person crew and a Luton for flats; three or four crew and two vans for houses with lofts, cellars or garages.
