The Engineers were not much slowed down by the loss of South Hall. The basement was still there. In fourteen working days they completed construction of a new engineering hall on top of the ruins. Known to engineers as the Engineering Shed (or just “The Shed”), the more architecturally sensitive called the structure “The Sheep Shed.” It is not known if the engineering library ever occupied any part of the original Shed. However, when it became known that the Medicals had no further need of “their” basement, the Engineers arranged to have a shed built over that too.
The floor plan of the “engineering halls” still exists. The engineering library is shown on the plan for the “medical” shed and can be seen at the arrow in the photograph.
