The housing stock
What we are usually working with in Colindale
There is nearly always a boxed soil stack or a service riser in a corner of the run, and it is rarely mentioned at enquiry. Taking the old tops off is also the first honest look at what has been going on underneath them. A sound carcass takes stone; a soft one gets replaced first.
Lift internal dimensions decide the maximum piece. Towers with booked goods lifts, concierge sign-in, insurance documentation and time-limited loading bays, and underground car parks with height barriers that stop a standard stone van. Measure the goods lift and the flat's front door before quoting, because on these blocks the building, not the kitchen, sets the largest piece you can deliver.
A tower block runs one or two lifts for many floors, so a lift out of service postpones a job rather than making it harder. The plaster is bonded straight onto the concrete, so the bottom course of tiles tends to bring plaster with it when the old top comes off, leaving a rough band behind the upstand. What is under the old top is the real question.
The building types here are 2010s-2020s high-rise apartment, regeneration low-rise and 1930s semi at the edges. The one you have sets the piece length before the kitchen does.

There is nothing to visit in Colindale. Samples are posted free, the template is taken in your kitchen and the stone is fitted there too.
