The housing stock
What we are usually working with in Shortlands
The rear wall of the addition carries both the back door and the window, which leaves very little unbroken wall for a run to sit against. What decides between a slim upstand and full-height stone is nearly always the wall rather than the taste. Siliconed to the top, never grouted.
Where a slab has to be walked down a set of steep front steps we bring extra hands rather than trolley it, because a drop on a stone tread here is a broken piece every time. The roads are hilly and narrow with parking on both sides, and several streets drop steeply from the road to the front door, so the carry is often downhill on wet steps rather than a flat approach.
Many of these had a bathroom or a WC built onto the far end of the addition, so the room now ends at a stud wall rather than at the original brickwork. A 100mm upstand bedded on silicone is the honest answer where the plaster bows, because it rides what a tall panel exposes. Decided before fabrication starts.
Around here the stock is Victorian villa, Edwardian semi, 1930s detached and 1960s low-rise flats. They fail in different places, which is why the survey looks at different things.
There is nothing to visit in Shortlands. Samples are posted free, the template is taken in your kitchen and the stone is fitted there too.
