Walk Holloway from The Emirates Stadium and Nag's Head market outwards and the mainly Victorian pattern is obvious: 89% of the 8,936 households in N7 live in flats, 11% in houses.
Private renting sits at 40% and owner-occupation at 29%; the first group books gym equipment assembly at short notice, the second plans it.
Walls are precast concrete panels and dense blockwork; locally that also means often with surface conduit — measured on the walk in from Holloway Road (Piccadilly) rather than assumed from a map, 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 on these streets — and with 35% one-person households in Holloway, one adult is usually the only pair of hands on site.
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 bikes, benches and rowers; two for treadmills, racks and multi-gyms, or wherever the machine must be carried above the ground floor. Fitters travelling in use Holloway Road (Piccadilly).
