The housing stock
What we are usually working with in London Fields
A cast iron soil stack runs down the outside of the rear wall, so moving the sink means a fresh penetration through solid brick. A run that has to be scribed twice takes an hour longer than one that does not, and the day is costed with that hour in it. Nothing is cut in the room if the shop could do it.
The streets around the park are permit-only, filtered and busy with pedestrians and cyclists, and market days make the Broadway Market end effectively impassable for a van.
The external wall on the passage side has never been rendered, so it is cold, solid and honest to fix into. The units are levelled and packed before a top goes near them, because a settled floor shows immediately in a long straight edge. Carried once, and carried properly.
What we are cutting for, here, is Victorian terrace, warehouse conversion, above-shop flat and post-war infill. None of them is harder than the others; they are awkward in different ways.
Access. Extension jobs usually allow a carry through the house or via a side gate straight into the rear.
There is nothing to visit in London Fields. Samples are posted free, the template is taken in your kitchen and the stone is fitted there too.
