The slab is laid out before it is cut
The template drawing arrives in the workshop and becomes a cutting plan drawn onto your actual slab. That step is called nesting, and it decides more about how the finished kitchen looks than the colour did. On a marble-effect quartz or a granite with real movement, nesting is what determines whether a vein runs across a join or stops dead at it.
Then the kitchen is built on the bench before it is built in your house. Runs are laid out together, joins pulled up tight, the sink dropped in and the hob offered up. Anything wrong is found there, where it costs an hour and a new cut, rather than in your kitchen where it costs a day, a slab and a fitting date.
Everything is machined to the template drawing, not to the plan and not to a tape measure taken on the day. This is the whole reason templating happens after the units are in.
Fitted 5–10 working days from template. Deposit at template, balance before installation.
