The N4 stock around Green Lanes and Finsbury Park's northern edge is period conversion. ONS records 66% flats, 34% houses and 12,105 households in Harringay.
Owner-occupation runs at 35% in Harringay, so alongside the 45% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Harringay substrates run to with solid brick on the party and external walls, over lath and plaster over timber studs — and with 45% of homes here privately rented, it sets the booking date as often as the job does. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in N4, which crumbles the key and drops the panel — with 20% social-rented stock locally, block access is agreed with the estate office first is the mistake that costs a N4 customer twice.
Two streets can behave very differently in Harringay: green Lanes' ocakbasi grills and the Harringay Ladder of parallel terraces. The quote reflects the street the job is actually on. Harringay is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
On access, the Ladder streets are narrow and fully permit-controlled; Green Lanes has short loading bays — one reason two to four operatives depending on severity, with PPE for biohazard handling and a plain, unmarked vehicle available on request.
