Kitchen worktops in South Bank

Yes. Predominantly apartment kitchens in managed buildings: an appliance wall plus a peninsula or a compact island, all within the developer's original layout and with no scope to move services. Stone is chosen to be seen from the living area rather than to work hard. Underground loading has a height restriction, and a van with an A-frame on it is taller than the driver remembers. Waste is the part people forget: the old laminate or tired granite has to be walked back to the van and it does not get lighter. Old tops out and new stone in, both through the same gap.

1980s co-operative housing, Riverside tower and Converted commercial building. A gated development controls when a van gets in, where it can stand and for how long, and none of that gets decided on the morning. The room itself is the easy part: walls are plumb, corners are square and the floor is flat, so scribes are minimal and joins can be tight. What is under the old top is the real question.

Everything moves through a service entrance with a booked goods lift, a signed-in delivery window and often a restriction on working before 9am or after 5pm. Riverside frontages have no vehicle access at all, so the loading dock is at the back of the building. The lift has to be booked and blanketed before anything moves, and that booking needs to cover the old tops coming out as well as the new stone going in. With no room to turn, the old top gets cut up in the kitchen instead, which is dusty work and needs the room emptied first. That is agreed before a plumber is booked.

Worktop replacement, worktop installation and worktop fabrication, in that order. Upgrading a builder-finish kitchen is mostly a swap, so the cost sits in the material choice rather than in the shape of the room. Cutting several kitchens from different slabs and calling them matched is where firms get caught out. Nested for the job in front of us. Buildings here have strict rules on wet cutting and dust, so any on-site adjustment needs extraction and a sheeted area agreed with building management in advance.

If the island is a few hundred millimetres longer than the usable length of a slab, a second slab gets bought to gain that overhang, and the whole slab is paid for rather than the part used. On the day that means dry-laying the whole layout first and only then pulling and bonding the joins. Dry-lay first, always. Where a partition has been built off the floor screed rather than off the slab, it moves, and a mitre bonded across that corner is the first thing to open. We would rather find it at template than on the morning, which is why the templater looks behind the units. It is the usual surprise, and it is a known one. Material runs from £110 per square metre supply only, and templating, fabrication and fitting are quoted on their own lines rather than rolled into one figure.

A street with houses in single occupation next to the same houses cut into flats produces two completely different jobs from the same elevation. Changing an appliance after the nest is set means recutting the piece, not adjusting it. The approved drawing is the instruction. Tell us the building when you book and the lift, the stair turn and any freeholder notice get built into the day rather than found on it.
