Worktop replacement in Barbican

Yes. Barbican is on the patch, and the postcodes we work here are EC2Y. It is worked on our the City run, along with the rest of the Square Mile. The realistic answer on a main road is an early slot, a spotter on the van and pieces staged in one movement rather than several trips. We stage the strip-out so the old tops leave in one trip rather than trickling out across the afternoon. Old tops out and new stone in, both through the same gap. We template in your kitchen and fit in your kitchen, so there is nothing to visit and nothing to collect.

Walls look modern and are not: block or breeze with a skim that has been patched over decades, so dry-laying and scribing still apply. The units are often 1970s or 80s and only around 500mm deep, so a standard 600mm stone top overhangs at the front and the doors and drawer fronts need checking against it. What is under the old top is the real question. Do a full dry run of the route from car park lift to flat door before ordering, because the Barbican's walk-in is longer and more awkward than any staircase in the City.

There is no vehicle access to the podium at all - you park in one of the estate car parks below, then use a car park lift and walk the highwalks and internal corridors, which can be several hundred metres with multiple fire doors and level changes. Lift cars in the residential cores are small with low ceilings, so anything over about 2.2m has to be assessed against the specific core before you cut. Piece length is set by the internal diagonal of the lift car, not by the length of the slab. Worth remembering that the old tops have to come out the way the new ones come in, and a laminate run is easier to remove in one length than to carry in one. That is agreed before a plumber is booked.

Yes. On the research for this patch it is the first of the three jobs listed, ahead of worktop templating and worktop splashbacks & upstands. A kitchen carved out of a larger room sits under whatever the original plan left behind, so the run frequently ends at a blocked doorway or a boxed-in service. The carcasses have to be sound, because stone is several times the weight of what is coming off. Sound carcasses or it does not go ahead. Conversions put kitchens where the services could be made to reach rather than where they belong, so runs are short and interrupted. The units stay and only the surface changes, so the whole job is one day rather than a kitchen refit. A day, not a project.

A galley puts the sink on one side and the hob on the other, which spreads the cut-outs across two pieces instead of weakening one. The existing layout is being kept, so the question is whether the old carcasses will take stone in that shape without more support. Carcasses have to be sound first. Material is £110-£550 per square metre supply only, and templating, fabrication and fitting are quoted on their own lines.

Floors settle, and once base units are packed and levelled properly the stone sits true while everything else in the room admits it is not. 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. Empty the base units completely and have a plumber disconnect the sink, tap and any washing machine plumbed in under the worktop before we arrive. An owner living in the house makes the decisions and lives with them, so the specification tends to go towards the material rather than towards the lowest total. A plumber disconnects before we arrive and reconnects after we leave, and that is worth booking early. Units kept, surface changed.
