Kitchen worktops in Bush Hill Park

Yes. This is side-return infill country - the original narrow galley in the back addition gets widened by 1.8m, which turns a 2.1m run into a 4m run plus a small island or peninsula. The conservation area limits what you can do to the front but the rear is where the money goes. Without a bay the van ends up on a single yellow with a crew member watching it, which takes a pair of hands off the carry. 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.

Edwardian garden-suburb semi, Victorian bay terrace and 1930s infill. The back addition is a narrow two-storey outrigger with a single external wall, and the kitchen galley runs the length of it. Lath-and-plaster and bowed brickwork mean we template for scribes rather than straight cuts, and each piece is offered up and eased in rather than dropped straight down. Units kept, surface changed, one day.

Roads are flat and wide but parked solid both sides thanks to the station controlled zone, so you often carry from 40-50m away. Front gardens are deep with a tiled path and a gate that needs lifting off. Garden routes carry their own hazards: a drain cover, a step up to a patio, wet decking, or a lawn that will not take a loaded trolley. Worth remembering that the old tops have to come out the way the new ones come in, and a laminate run is easier to remove in one length than to carry in one. The strip-out is planned around it.

Worktop templating, worktop installation and worktop replacement, in that order. A new extension slab is not automatically level, and that wants checking before templating rather than after the stone is cut. The template visit is booked once the units are genuinely in, not when they are nearly in. The room as it is, not as it was drawn. In an infilled side return the new run crosses the line of the old external wall - check for a level step and a soft spot in the floor before you template, because a 4m slab will telegraph any dip.

Two parallel runs with a walkway between them is the most efficient shape there is on a slab, because both pieces nest as straight lengths with almost no waste. Old laminate has often been holding a run square for years, and taking it off shows what the units were really doing. The units stay, the surface changes. A run can measure dead right at both ends and still belly out in the middle, which only appears once the template plots the intermediate points. The template plots it as it is, at the exact height the worktop will sit, and the drawing carries that through. Measured at worktop height, nowhere else. 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.

Where ownership is split across a building, the common parts belong to someone else and the carry route is negotiated rather than assumed. The template happens when the units are in, fixed and level, whoever is fitting them. Fitted, fixed and level, then we come. 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.
