The letter on the plan was the spec
The original houses here are still known locally by their letters, and the letter told you what you were getting. Skidmore, Owings and Merrill, one of the principal designers of housing in Oak Ridge, laid the houses out on the sequence of the alphabet, so an earlier letter generally meant less square footage and fewer features while a later letter was more likely to be a family house. Alongside the cemesto types ran the Flat-Tops, in their own A, B, C, S, and V designs. All of it was drawn for speed: the planners had estimated 13,000 workers and the population was heading for 75,000 instead. Eight decades on, that standardization is still readable from the street. A letter tells you a good deal about what is behind the door, from the room count and the ceiling height to the closet layout and the amount of painted trim, before anyone opens it. What it mostly tells you is that there are a lot of edges for the floor area. Small rooms each carry their own baseboard run, their own door casing, and their own window, and every one of those is hand work.
