In Bloomsbury (WC1) the split is 95% flats to 5% houses over 6,576 households, and the stock is Georgian and early Victorian.
Because 38% of Bloomsbury is privately rented and 42% socially rented, a lot of WC1 work is agreed with a landlord or managing agent rather than the person opening the door.
Bloomsbury substrates run to precast concrete panels and dense blockwork in Bloomsbury, often with surface conduit, and with 47% one-person households in Bloomsbury, one adult is usually the only pair of hands on site. Nothing is drilled until the wall has been sounded, because Bloomsbury gives us drilling blind into a panel with reinforcement or a buried cable behind it, the reality on the streets around The British Museum is the mistake that costs a WC1 customer twice.
Garden squares, university faculties and the British Museum's streets of Georgian terraces. That character decides the practical detail of shed assembly here far more than the borough boundary does. Bloomsbury sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
Camden CPZ all week, listed staircases and squares where loading needs a bay suspension. Nearest station is Russell Square (Piccadilly), and one fitter for a small shed on a ready base; two for anything over 8x6ft or where roof panels need lifting together.
