The housing stock
What we are usually working with in Spitalfields
Suspended timber floors flex underfoot, and anything that moves beneath a unit shows up later as a lipped join. The workshop works to the template drawing and to the measured route, in that order. Yield is worked out against the run lengths the house allows.
Most of the area is a conservation area with a high concentration of listed houses, so any fixings into original fabric and any external hoisting need consent and a careful method. Streets are narrow, largely pedestrianised near the market and loading windows are early morning only, with staircases inside the houses that are steep, winding and original. You cannot cut a listed house to suit the stone, so the stone gets templated and jointed to suit the house, including a joint mid-run just to get it down the stairs.
A basement kitchen has a flagged or concrete floor laid straight onto the ground, so it is solid, cold and rarely within ten millimetres of level. Joins land over a cabinet gable and clear of every cut-out, because the alternative is a bridge of stone that will not survive the carry. What leaves the bench is what fits the room.
What we are usually templating in is early Georgian silk weavers' house, Victorian warehouse conversion and 1970s-80s infill flat. They fail in different places, which is why the survey looks at different things.
There is nothing to visit in Spitalfields. Samples are posted free, the template is taken in your kitchen and the stone is fitted there too.
