The building, and what it does to the job
Locally the stock leans newer than the London norm. The sink and hob are seated and sealed before we leave; we do not connect water, waste, gas or electrics. The route is walked before the first piece moves.
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. The boxing round the risers is measured again with the old top off, because the last fit was often built around it. Sound carcasses are the one condition.
Extension floors here are often laid before the units go in and settle unevenly, so the base cabinets need packing and re-levelling on template day or the joint on a long run opens up.
Sill height gets settled with the template on site, because it is one of the few dimensions nobody has measured before we arrive. Sealant is not a way of fitting it, so the scribe is cut until it closes and the silicone only has to seal. A forced back edge cracks weeks later.
