This is it! I picked it up from the builder today. It's a set of six individual boxes, each with their own door. These will be collected in a couple of weeks as I'm having the windows altered. I'm not sure yet whether to use the stairs, I'll see how things go with the interiors. The whole thing is approximately 10" wide by 5'6" high.
I plan on having a shop on the ground floor, with a kitchen, merchant, two spinster sisters, a Judge/Lawyer, a Gentleman and a tradesman all included. Such was the diversity of these buildings.
