Walls are precast concrete panels and dense blockwork in Bloomsbury, often with surface conduit — which is why London Borough of Camden kerb rules get settled before the van is loaded, so the fixing that matters in Bloomsbury is chosen on site — the usual failure here is in WC1, drilling blind into a panel with reinforcement or a buried cable behind it — and with 47% one-person households in Bloomsbury, one adult is usually the only pair of hands on site.
