The housing stock
What we are usually working with in Chelsea
Injected damp courses and re-rendered lower walls leave the bottom metre standing proud of everything above it. The units stay and only the surface changes, so the job is a day, and what makes it a difficult day is the building. The old top comes off in pieces, not whole.
Many of the older houses are listed, which rules out taking out a window or a sash to bring stone through, and the front doors are period joinery that nobody will let you unhang. Listed frontages mean the stone comes through the existing door opening or not at all, so template to the doorway first and the kitchen second.
A basement kitchen has a flagged or concrete floor laid straight onto the ground, so it is solid, cold and rarely within ten millimetres of level. What the old top has been hiding is usually a floor that settled towards the back and units that were never fixed back to the wall. Chipboard that has taken water will not take stone.
The stock behind these kitchens runs to Georgian riverside terrace, early Victorian cottage terrace, Cadogan Estate red-brick mansion block and 1930s purpose-built flats. Which of those you have decides most of what follows.
Access. Estate-managed blocks impose their own works hours and require notification to the managing agent, and the King's Road itself has loading restrictions through the day.
There is nothing to visit in Chelsea. Samples are posted free, the template is taken in your kitchen and the stone is fitted there too.
