Each side was 7 (I think) hollow 300sq ft concrete rooms, circular. We had forced air circulation, and AC in the "datacenter" tower (which was 2 rooms of datacenter, some power conditioning, and a NOC); just forced air in the residential one (and some heating using electrical heaters).
During the war, those towers were where people lived, and the lowest levels were shell magazines for the big AA guns (3.9"?). They had a bigger superstructure, too. I absolutely would not have wanted to have been there with 300 people; even with 6-10 it was pretty bad.
