The housing stock
What we are usually working with in North Kensington
The rear wall of the addition carries both the back door and the window, which leaves very little unbroken wall for a run to sit against. Cutting sockets and switch plates into stone is a workshop operation, so the electrics have to be final before the template. Making the wall good first is cheaper than working around it.
Levels are the recurring problem in the back additions - the floor drops away from the house so the base units are packed and the worktop is the only thing hiding it. Estate deliveries need the block entry code and often a lift key from the caretaker, and several blocks have a stepped podium between the parking and the entrance door. On the terraced streets the bays are resident-permit with short loading tolerance, so plan a two-vehicle approach: van in, unload, van out.
There is a solid base under the old scullery end and suspended timber where the addition meets the house, and the two part company along that joint. The units are levelled and packed before a top goes near them, because a settled floor shows immediately in a long straight edge. The shell has the last word on fitting day.
Most of what we quote on here is Victorian terrace in multiple occupation, postwar council estate, 1960s slab block and recent housing association infill. Each of those behaves differently once the old top comes off.
There is nothing to visit in North Kensington. Samples are posted free, the template is taken in your kitchen and the stone is fitted there too.
