In Holloway (N7) the split is 89% flats to 11% houses over 8,936 households, and the stock is mainly Victorian.
Because 40% of Holloway is privately rented and 31% socially rented, a lot of N7 work is agreed with a landlord or managing agent rather than the person opening the door.
Walls are often with surface conduit — and precast concrete panels and dense blockwork, the pattern behind 8,936 households inside the N7 neighbourhood, so the fixing that matters in Holloway is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it, as the Holloway stock goes, a median age of 32 in this neighbourhood shapes what gets ordered here.
A busy road of shops and student halls, with quieter Victorian streets either side. That character decides the practical detail of wood flooring here far more than the borough boundary does. Holloway sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Getting to the door matters as much as the job: holloway Road is a red route; side streets are permit-only with tight corners. Holloway Road (Piccadilly) is the nearest station, and one fitter for a floating fit in a single room; two for glued or secret-nailed floors and any job over 25m² in a day.
