This is the site plan for the building--note that K Street was extended all the way from UD west to S. Patterson Blvd. Building 26 was isolated from the factory buildings--a fact that aided in guarding the installation once the Navy took over the building.

A large wooden supply shack was built out the east or back side of the building during the war, to house the huge inventory of hardware and electrical supplies that were needed for the manufacture of the bombes. A railroad siding, or spur, was convenient to the shed. To the west, once the bombes were ready for shipment in late August 1943, another shed had to be built connected to the front of the building. The front doors (see above) were the only way for the large machines to leave (the back doors were too narrow; since the building was meant to house classrooms, it had no loading dock), so the shed hid the machines from view as they were loaded onto a trailer truck. The truck then pulled around to the railroad sidings behind the building and from there the machines were loaded onto rail cars. Marines guarded the transfer (I've been told that these were the only times there were Marine marksmen on the roof), and two Navy seamen would ride on each car with them on the journey to Washington.

Bob Roeckner, who was hired fresh from from high school to be a stockboy for Building 26, says that the rooms retained their classroom appearance despite their uses as offices and machine shops--chalkboards were usually cluttered with diagrams and calculations. Joe Desch has his desk at the far side of his room, and a large table near the door served as a place for frequent, heated meetings (minutes for several of those meetings exist at the National Archives).
