Woolwich kitchens
The kitchens we meet in Woolwich
Anyone who has already replaced a kitchen in Woolwich will tell you that splashback and upstand work is decided by the room long before anyone opens a colour chart. A lot of ex-local-authority flats and maisonettes with small closed kitchens, single or double run at 2.4m to 3m and no room for an island, alongside regeneration blocks with open-plan peninsulas. Most work is like-for-like replacement into existing units rather than a redesign. None of that changes what you pay in Woolwich. The figure is set at template and it holds from there.
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. Socket positions, sill heights and wall flatness are the three things that settle this, and all three are properties of the building. Panel joints land over a unit line, never mid-span.
Many were built with a solid sub-floor to the rear rooms, so the kitchen floor is concrete and level while the front of the house is suspended timber. 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. The tile bed comes off before anything is measured.
The building types here are Victorian terrace, 1960s council tower, 1970s low-rise estate and 2010s regeneration block. The one you have sets the piece length before the kitchen does.
