There is an old brick workshop at the bottom of my garden. Can that go?

Possibly, but check first. Northampton has a lot of these, left over from the boot and shoe trade when outworkers made shoes in small workshops behind the terrace. Plenty survive around Far Cotton, St James, Kingsley and Semilong. Some are locally listed, some sit inside a conservation area, and a few are the reason the conservation area exists. Get the council’s view before anything comes down, because a demolished one cannot be put back. In some cases, repairing it beats replacing it, and we will say so if that is what we think.
