The building, and what it does to the job
In Cockfosters, hardly any of it is newly built, so what the old surface was fixed to matters more than what goes on top. It decides how many hands the day needs, which is the part people find out late. What the survey found is what gets carried in.
The windows were steel to begin with and have been swapped for plastic in openings lined out to suit, so the reveal is now deeper than the brickwork behind it. Where a full length can come down the side and in at the back, the nest follows the slab instead of the building. The shell decides the piece; the slab decides only the yield.
Where the kitchen opens into a garden room, the run often ends at a glazed corner with no wall to scribe against, so the exposed end needs a fully polished, matched edge.
