Where the floor stops matters more than most people expect
One of the first questions in a kitchen is whether the flooring runs under the cabinetry or stops at it. It sounds like a detail. It determines what a future appliance swap costs, whether a dishwasher can be pulled without damaging the finish, and how the toe kick reads along the run.
There is no universally right answer. There is a right answer for a specific kitchen, a specific product and a specific expectation about what will change in five years.
What is not optional is deciding it before installation, rather than discovering it when the first appliance has to come out.
The transition to the rest of the house
A kitchen almost never has its own floor in isolation. It opens to a living area, a hallway, a laundry room or an exterior door, and each of those is a line where two decisions have to agree.
We plan those lines with the flooring layout rather than treating them as trim applied at the end. Where the material changes, the change is placed deliberately, usually at a threshold the eye already reads as a boundary, not in the middle of an open sightline.
That is why the flooring conversation and the cabinetry conversation are the same conversation for us.
