Before you settle on a material, it is worth understanding how worktop installation in Whalebone is shaped by the room it has to go into. The strip between Chadwell Heath and Becontree Heath, mixing estate housing with privately built inter-war semis, so kitchen sizes vary within a couple of streets of each other. Most jobs are moderate: a new set of units in the existing footprint, a 3m run and a short return, with a peninsula only where the dining room wall has already gone. If your kitchen is a bit of both, that is common enough and it changes nothing about how we go about it.
A fob on the communal door and a shared lift mean the carry is timed rather than continuous. A run that has to be scribed twice takes an hour longer than one that does not, and the day is costed with that hour in it. A bad floor is corrected under the carcass, never with sealant.
Door openings and the hall were set to a generous standard, so a long piece turns in from the front without being stood on end to do it. Carcass heights are corrected on the day where legs have bottomed out, because a top will not bridge a step between units. Fixings go into what the wall actually is.
Around here the stock is 1930s semi, LCC estate house and post-war infill. The differences between them show up at template, not at enquiry.
