The N7 stock around The Emirates Stadium and Nag's Head market is mainly Victorian. ONS records 89% flats, 11% houses and 8,936 households in Holloway.
40% of households rent privately and 29% own, which is why flat-pack assembly demand here peaks around tenancy changeovers and completion dates.
Walls are precast concrete panels and dense blockwork in N7, often with surface conduit — the reality on the streets around The Emirates Stadium and Nag's Head market, so the fixing that matters in Holloway is chosen on site — the usual failure here is in N7, drilling blind into a panel with reinforcement or a buried cable behind it — measured on the walk in from Holloway Road (Piccadilly) rather than assumed from a map.
Two streets can behave very differently in Holloway: a busy road of shops and student halls, with quieter Victorian streets either side. The quote reflects the street the job is actually on. 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.
On access, holloway Road is a red route; side streets are permit-only with tight corners — one reason one fitter for most items; two for sliding-door wardrobes, bunk beds and anything that has to be carried up a shared stairwell. Fitters travelling in use Holloway Road (Piccadilly).
