Stone worktops in Greenhill

Yes. Greenhill is on the patch, and the postcodes we work here are HA1. It is worked on our north west London run, along with the rest of Harrow. Where the bay sits some distance from the core, the carry across the car park is the longest leg of the day and gets boarded and lit. Whatever the standing allows, the stone leaves that van finished, because every edge, cut-out and internal radius is machined at the works and none of it is open to reconsideration at the kerb. Nothing about the shortlist is decided on the day itself. Everything that involves you happens in your kitchen, so there is nothing to visit and nothing to collect.

Floor to ceiling height is tight once the raised floor and the suspended ceiling are allowed for, so wall units sit close down onto the worktop. Light is almost entirely artificial and frequently cool, which pushes warm creams towards grey and makes a genuinely neutral colour the safer choice under bulbs that are already in the ceiling. True walls and standard carcasses give the best yield there is. Boxing is rarely the same depth at worktop height as it is at floor level, so measuring it low down is the usual reason a top will not sit back. Every notch and every scribe is machined into the piece before it leaves the works, and a hard sintered surface is the least forgiving of a tight internal corner, so one is always cut with a generous radius. Every notch is machined on the bench and none on site.

Concierge buildings want the goods entrance, a booked lift and proof of insurance, all of which is straightforward when it is asked for a week out. That caps the longest piece, and a run split into two lengths nests differently on the slab, which moves the yield and moves the figure with it. The seam is planned on the layout, not discovered in the room. The goods lift has its own booking sheet, and a bay slot without a lift slot only gets the stone as far as the lobby. A granite kitchen ends its day with a sealer, and a sealer wants a dry face and a quiet hour afterwards, so that hour is written into the day rather than borrowed from it. A figured slab takes longer to match than a plain one.

A window at one end and a doorway at the other means one end of the run is lit from behind and the other is interrupted, so the two ends of the same length behave differently. A shape like that nests kindly on a slab, so more of what gets bought ends up on the units and the rate per square metre behaves much as the brochure says it will. Two mitres and three lengths is bench work, not surface area. Material sits between £110 and £550 per square metre supply only, and templating, fabrication and fitting are quoted line by line.

Anything that has to stay accessible, a stopcock, a gas meter, a riser panel, is marked on the template so the stone is cut around it instead of over it. A hob dropped into the middle of a length puts sustained warmth at the lip of a cut-out, and an engineered surface will yellow there across ten years where a natural one takes it without comment. Water standing daily is what makes porosity matter. Send the kitchen layout with run lengths and the peninsula projection if there is one, and tell us what the lift will take as a single piece. Two flats with an identical layout can want entirely different things from the same run of worktop, which is why the quote follows the run rather than the address. That changes which questions are worth asking about the stone, because somebody staying put wants to know how a honed face marks in five years and somebody selling wants to know how it photographs next spring. A chip in natural stone can be filled and polished in place.

On the fitting day floors and door frames are protected, joins clamped flush, sink and hob sealed. The same firm templates and fits. Nobody else is brought in to install. The template produces a drawing, and the workshop cuts to that drawing once you agree it. Underfloor heating in a screed rules out fixing into the floor and rules out standing anything heavy on a single point. Which stone belongs on top of all that is a separate question from the building itself, and it is the one with a figure attached, because supply alone runs from £110 to £550 per square metre before a single cut has been made. Yield is the word behind most quotations people did not expect.

Dark and heavily veined stone shows a join more than a pale even one, which is worth knowing before the slab is picked. There are only ever a few legal positions, and the one taken is furthest from the light. A join cannot cross a cut-out, so a sink mid-run takes away the position you would have used. The two runs are rarely the same length, and the shorter one often carries the sink, which puts the cut-outs in the piece with the least material to spare. An island is the piece that decides whether one slab covers the kitchen or two, and a second slab arrives as a step in the figure rather than a gentle slope. A single straight run is the cheapest stone you will ever buy.

The lift, if there is one, is measured on the diagonal, because that is the dimension a long piece actually uses. Splitting a run costs a join, and that is the price of getting stone into the room at all. Bollards, planters and a one-way service road can turn what looks like a ten-metre carry into a fifty-metre one. Sintered stone at twelve millimetres weighs roughly half what thirty millimetre granite weighs, so a punishing route can genuinely rule one material in and another out. The pieces either side of a break come off adjoining slab.

The joint between splashback and worktop is siliconed, never grouted, so it can move a little without cracking. A full-height piece behind the hob has to allow for the extractor, so that gets settled first. If it is a decision for later, say so at the template: the match is a question about the batch. A raised access floor may still be in place under the finish, and it is hollow, so an island is fixed to what is below rather than to the deck. Kitchens in a block like this are compact, so the total area is modest and the material band moves the figure far more than the metreage ever does. A kitchen with no window of its own needs tone rather than colour.
