In Paddington (W2) the split is 87% flats to 13% houses over 3,981 households, and the stock is period conversion.
The renter-heavy mix here (30% owned, 54% privately rented) means a W2 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are with metal stud partitions between rooms — and dot-and-dab plasterboard over blockwork, and with 45% one-person households in Paddington, one adult is usually the only pair of hands on site, so the fixing that matters in Paddington is chosen on site — the usual failure here is short screws that grip only the board and slowly lever it off the dabs, as the Paddington stock goes, where 30% owner-occupation means the same home is booked again rather than a new tenant each year.
Canal basin offices and hotels beside Bayswater's stucco terraces and Hyde Park. That character decides the practical detail of shed assembly here far more than the borough boundary does. Paddington 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: basin estate loading bays, red routes on Bishop's Bridge Road and stucco terraces with basement steps. Paddington (Elizabeth line, Bakerloo, Circle, National Rail) is the nearest station, and one fitter for a small shed on a ready base; two for anything over 8x6ft or where roof panels need lifting together.
