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.
South Bank and Waterloo substrates run to often with surface conduit, over precast concrete panels and dense blockwork — with 31% social-rented stock locally, block access is agreed with the estate office first.

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.
Riverside pedestrian zones, red routes on Stamford Street and event-day closures. Nearest station is Waterloo (Jubilee, Northern, Bakerloo, National Rail), and four crew and a supervisor on a standard floor clearance, scaled up for phased overnight work.
