The housing stock
What we are usually working with in Harlesden
Gas, waste and later wiring were boxed in against the wall long after the house was built, and that boxing is what the run has to clear. Height is set off the units and the hob, not off the tile line that was there before. A return into a reveal is its own scribed piece.
Many of these had a bathroom or a WC built onto the far end of the addition, so the room now ends at a stud wall rather than at the original brickwork. Lath-and-plaster on the party wall and the chimney breast returns almost never runs true, so a 100mm upstand bedded on silicone is the honest answer here, it rides the bow and hides the junction the worktop can never close on its own. Solid plaster on brick takes a panel; a hollow wall wants thought.
On this patch the buildings are Victorian bay-fronted terrace, Edwardian terrace and post-war council block. The differences between them show up at template, not at enquiry.
Access. No driveways to speak of, red route and bus lane restrictions on the main roads, and controlled parking on almost every side street, so a dispensation or a very early start is usually needed to get the van close enough for a hall carry.
There is nothing to visit in Harlesden. Samples are posted free, the template is taken in your kitchen and the stone is fitted there too.
