The EC3 stock around The Royal Exchange is period conversion. ONS records 98% flats, 2% houses and 4,914 households in Bank and Cornhill.
Owner-occupation runs at 37% in Bank and Cornhill, so alongside the 48% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Bank and Cornhill substrates run to with metal stud partitions between rooms, over dot-and-dab plasterboard over blockwork — which is what a 98% flat share across the ONS neighbourhood covering Bank and Cornhill actually produces. Nothing is drilled until the wall has been sounded, because in EC3, short screws that grip only the board and slowly lever it off the dabs — and with 51% one-person households in Bank and Cornhill, one adult is usually the only pair of hands on site is the mistake that costs a EC3 customer twice.
Two streets can behave very differently in Bank and Cornhill: the historic financial heart — Royal Exchange, Mansion House and the alleyways behind Leadenhall. The quote reflects the street the job is actually on. Bank and Cornhill 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, bank junction is closed to most traffic on weekdays — early-morning or weekend access only — one reason two crew and a Luton van; three where a wardrobe or corner sofa has to come down a shared stairwell. Fitters travelling in use Bank (Central, Northern, Waterloo & City, DLR).
