The building, and what it does to the job
Locally the banding is well below the London middle. The units stay and only the surface changes, so the whole job turns on what the carcasses will take. Measured after the old surface is off, where it matters.
A drying balcony opened off the kitchen originally and many have since been glazed in, which turns an external wall into an internal one with the old threshold still in it. The carry is the constraint. What the building will take decides how it is fixed.
Waterside blocks have long internal corridors from the lift to the flat door, so the carry inside the building is often longer than the one outside it.
