Walk South Bank and Waterloo from The National Theatre and Tate Modern outwards and the post-war pattern is obvious: 94% of the 4,696 households in SE1 live in flats, 6% in houses.
Owner-occupation runs at 24% in South Bank and Waterloo, so alongside the 44% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Expect precast concrete panels and dense blockwork in SE1, often with surface conduit — which is what a 94% flat share across the ONS neighbourhood covering South Bank and Waterloo actually produces behind the plaster in SE1. That is why fixings are picked in the room rather than off a van shelf, and why in SE1, drilling blind into a panel with reinforcement or a buried cable behind it — with 31% social-rented stock locally, block access is agreed with the estate office first is the fault we are called back to undo.
Two streets can behave very differently in South Bank and Waterloo: cultural riverfront from the National Theatre to Tate Modern, with Waterloo's flats behind. The quote reflects the street the job is actually on. South Bank and Waterloo 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, riverside pedestrian zones, red routes on Stamford Street and event-day closures — one reason two crew and a Luton on a standard mattress and base; the same crew dismantles bunk frames and storage divans on site before the carry. Fitters travelling in use Waterloo (Jubilee, Northern, Bakerloo, National Rail).
