The SW15 stock around The Alton Estate and Richmond Park is inter-war. ONS records 75% flats, 25% houses and 9,539 households in Roehampton.
Owner-occupation runs at 35% in Roehampton, so alongside the 25% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Walls are often with surface conduit, over precast concrete panels and dense blockwork — which is what a 75% flat share across the ONS neighbourhood covering Roehampton actually produces, so the fixing that matters in Roehampton is chosen on site — the usual failure here is in SW15, drilling blind into a panel with reinforcement or a buried cable behind it — with 40% social-rented stock locally, block access is agreed with the estate office first.
Two streets can behave very differently in Roehampton: the Alton Estate's modernist slabs beside Richmond Park's Roehampton Gate. The quote reflects the street the job is actually on. Roehampton is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Slab blocks with limited lifts, long walkway carries and steep estate approaches. Nearest station is Barnes (South Western), and two operatives as standard, one in the loft and one on the ladder and ground floor, which is how a loft clear stays safe rather than a one-person job with a rope and a prayer.
