Census 2021 puts Roehampton at 9,539 households with a median age of 33.4. The inter-war stock is social-housing-led, which is why 25% houses and 75% flats need different handling in SW15.
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 — the reality on the streets around The Alton Estate and Richmond Park, 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 — the pattern behind 9,539 households inside the SW15 neighbourhood.
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.
Getting to the door matters as much as the job: slab blocks with limited lifts, long walkway carries and steep estate approaches. Barnes (South Western) is the nearest station, and one fitter for standard windows; two for bent bay tracks or full-height stairwell blinds.
