The housing stock
What we are usually working with in Streatham Common
A picture rail, a deep skirting and a moulded architrave all sit in the way of anything that assumes flat wall from floor to ceiling. 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.
Full-height splashback panels behind a range need the flue and bracket positions confirmed first, because a 900mm tall panel with a badly placed cutout cannot be salvaged. Parking is easier than on the high road but the gradient makes trolley work risky when wet.
Wider halls make the carry noticeably easier, and that alone can remove a join that a narrower terrace would have forced into the run. A 100mm upstand bedded on silicone is the honest answer where the plaster bows, because it rides what a tall panel exposes. The age of the plaster decides the fixing, not the finish.
The stock behind these kitchens runs to Large Edwardian semi, Victorian villa, 1930s detached and Interwar block. The one you have sets the piece length before the kitchen does.
Access. Roads rise steeply away from the common with stepped front gardens and long paths, so the carry involves several steps up before the front door.
There is nothing to visit in Streatham Common. Samples are posted free, the template is taken in your kitchen and the stone is fitted there too.
