Northumberland Park kitchens
The kitchens we meet in Northumberland Park
Whatever you have read about splashback and upstand work in Northumberland Park, the only version that matters is the one measured against the kitchen you are standing in. Heavily estate-based - low-rise blocks and maisonettes with small separate kitchens, typically a 2.1m run plus a 1.2m return, wall boiler, and a larder cupboard that clients want kept. Regeneration flats nearby are open-plan with a single wall run and no island. The tape measure decides it, not the description above, and not anything anybody says over the telephone.
The original units were screwed to timber grounds set into the wall, and where those were torn out the plaster was patched rather than replaced. Socket positions, sill heights and wall flatness are the three things that settle this, and all three are properties of the building. Height off the units, not off the old tiles.
The external wall is a concrete panel with a modest window, so the run under it sits in a shallow reveal with a hard cill. A short band of wall over the sink is often better filled by one panel than by an upstand and a strip of tile above it. A hundred millimetres covers more than it looks.
The buildings themselves are mostly post-war council block, 1960s low-rise estate, Victorian terrace and regeneration new-build. A quote that ignores which one you have is guessing.
