The building, and what it does to the job
Locally the bands run low by London standards. The sink and hob are seated and sealed before we leave; we do not connect water, waste, gas or electrics. Fitted to the survey, checked against the room.
The addition is one room wide, so the run is a galley with a door at one end and a window at the other and no wall long enough for anything else. Joins land over a cabinet gable and clear of every cut-out, because the alternative is a bridge of stone that will not survive the carry. What the wall does is on the drawing before the saw runs.
Bifold walls mean the run gets broken and the island carries the sink or hob, so island support and overhang detailing need working out at design stage.
