Kitchen worktops in Bowes Park

Yes. Tight grid of Victorian terraces where most houses have been split into a ground-floor and a first-floor flat. Ground-floor flats get the back addition kitchen with a side-return infill if the owner has money; upper flats have the kitchen wedged into a back bedroom with a 2.2m run and a boiler cupboard. Permit hours are what matters, not the permit itself, because a bay that frees up at six in the evening is no use for a template at ten. The fitting slot is set around it, which is why we ask about it when the date is booked and not before we leave the yard. It is why the arrival time is what it is.

Victorian terrace, Edwardian terrace and flat conversion. Where the side return has been filled in, the old external wall is now an internal one and still carries its render, its gutter line and its old fixings. Victorian party walls and chimney-breast returns bow along their length, so the template plots the real line rather than assuming a straight one - the template picks up points every few hundred millimetres down the back of the run and the drawing carries that curve through to the saw. Recorded as it is, not as it was drawn.

No front gardens to speak of and doors almost straight off the pavement, permit parking all day, and the railway cuts several streets so you cannot always drive round the block. Upper conversions have no lift and a narrow original staircase. Stone goes up on edge, and it is the half-landing turn rather than the flight itself that sets the maximum piece. The templater measures that route on the same visit, so the drawing leaves site already knowing the maximum piece. The template records it along with everything else.

Worktop replacement, worktop templating and worktop installation, in that order. In a converted house the flat entrance and the internal doorway are usually tighter than the communal stairs, and that is easy to overlook. The units stay and only the surface changes, so the whole job is one day rather than a kitchen refit. A day, not a project. Upper-floor conversions above 2.4m of straight run need the top jointed at the stair - carry the pieces separately and joint in the room.

Galley runs are usually short enough to come out of a single slab, so the material band you choose does more to the total than the room shape does. A layout that has been packed and levelled run by run instead of to one datum shows as a step where two pieces meet. Dry-lay first, always. A boxed soil stack or service riser in the corner of a run eats into the worktop depth and has to be scribed around rather than cut square. On the day it means dry-laying, marking, and cutting the scribe on site before anything is bonded. Dry-lay, mark, cut, then bond. Material runs from £110 per square metre supply only, and templating, fabrication and fitting are quoted on their own lines rather than rolled into one figure.

A street with houses in single occupation next to the same houses cut into flats produces two completely different jobs from the same elevation. If the carcasses are tired the honest answer is that stone will find that out, and it is better said before than after. Units kept, surface changed. Tell us the building when you book and the lift, the stair turn and any freeholder notice get built into the day rather than found on it.
