Bigger rooms run to islands, and an island is a slab-yield question before it is a design one. Quartz slabs are a known size, so we can tell you early whether the island costs one slab or two. Nothing to seal on the day, and nothing to seal later.

These houses were built in long runs by the same builder, so the shell repeats. What has been done inside them since does not. The cut list carries it; the specification does not change.

The middle half of our quartz range runs from £150 to £270 per square metre, across 69 colours. In a large room the question is how many slabs the cut list needs, because an island that spills onto a second slab moves the price more than any extra metre of run.

Across Barnet's 31 neighbourhoods, the share of homes that are flats runs from 12% in Arkley to 86% in Colindale, with Childs Hill (73%) and Finchley Central (67%) next. Where the kitchen is up a flight, each quartz piece is sized to the stairwell before it is sized to the room.

Across Barnet's 31 neighbourhoods, the share of homes in converted or shared houses runs from 2% in Arkley to 19% in Golders Green, with North Finchley (16%) and Brent Cross (16%) next. A conversion usually means a stair that turns and a kitchen made out of another room, so the quartz is cut from a template taken once the units are in.

Free samples are posted for the Worktop Worx quartz collection; other quartz is judged from the slab.
