Ask where joints are proposed and why
Review a plan showing every join. Ask which positions are proposed because of the material, dimensions, support or handling arrangements, and which can be adjusted for appearance. A clear drawing is more useful than a general promise that joints will be discreet.
Do not assume a completely joint-free design is practical. We need to consider available slab dimensions and the route into your property. Give accurate access information early enough for it to influence the plan.
Agree what matching means
“Matching veins” can describe several levels of coordination. Ask to see how the selected pieces will meet and which pattern changes remain visible. For a natural stone, work from the actual slabs being reserved; for a manufactured design, review the relevant slab pattern.
Make your priorities clear. You may care most about the main island face, the longest worktop run or a splashback behind the hob. Knowing this helps us explain the available choices and any cost implications.
Review vertical and horizontal faces together
A waterfall end or full-height splashback creates another visible plane. Ask to review these alongside the worktop rather than as separate pieces. Confirm which direction the pattern runs and how the corners and exposed edges will be finished.
Include sink and hob openings in the review. The part of a slab removed for an opening can change the apparent balance of a strong pattern. A marked layout helps you understand what will remain in view.
Approve the plan before cutting
Keep the agreed drawing or slab-layout image with the written order. Ask how approval is recorded, what tolerances apply and how later changes are handled. Do not treat a mood-board image as a precise fabrication instruction.
For a new island, start with the island guide. For the installation sequence, see templating and fitting. Resolve the important visual decisions while there is still an opportunity to adjust the design.
