The building, and what it does to the job
In Swiss Cottage, the great majority of homes sit in blocks rather than on their own plot. A stone top leaves in sections, and getting those sections down the stairs is where the labour goes. The replacement fits the kitchen that is there now.
Permitted works hours are commonly weekdays with a late start and an early finish, so a one-day fit is planned around the porter and the lift. Waste from the old top goes down in loads the lift and the building will accept rather than in one trip. Nothing goes back on carcasses the building has pulled out of square.
Interwar block kitchens sit on a solid concrete floor with a boxed-in soil stack in the corner, so allow for a notch and a scribe rather than assuming a clean 90-degree return.
