The building, and what it does to the job
On the Friday Hill streets we cover, most of the stock dates from the building boom of the twenties and thirties. Repeated stock means repeated units, and if they are sound the rest is straightforward. What is underneath decides the day more than what is on top.
The communal stair is concrete with a metal handrail and a solid half-landing wall, so there is nothing to take off to gain a few millimetres. Carcass heights are corrected on the day where legs have bottomed out, because a top will not bridge a step between units. The units are shimmed to one datum before stone touches them.
Upper maisonettes are an external stair carry with an outside turn at the top, so wet weather changes the plan more than the dimensions do.
