Walk Harrow from Harrow School and St Mary's Church outwards and the mainly Victorian pattern is obvious: 38% of the 14,108 households in HA1 live in flats, 62% in houses.
Owner-occupation runs at 59% in Harrow, so alongside the 31% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Walls are solid London stock brick in HA1, some of it dry-lined during a later refurbishment — and one-way town centre with timed loading; the hill lanes are narrow and steep, so the fixing that matters in Harrow is chosen on site — the usual failure here is fixings landing in soft lime mortar joints instead of the brick body on these streets — which is what a 38% flat share across the ONS neighbourhood covering Harrow actually produces.
Anyone who knows Harrow knows the pattern near Harrow School and St Mary's Church: town centre shopping, St Ann's mall and the school on the hill above. We plan the HA1 visit around it. Harrow is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
One-way town centre with timed loading; the hill lanes are narrow and steep. Nearest station is Harrow-on-the-Hill (Metropolitan, Chiltern), and two crew and a Luton on most strip-outs; three crew and a tipper where the load is rubble, hardcore or soil and weight rather than volume decides the run.
