Between them are the pens, all save south pen extended c.1980 with lightweight steel structure to cope with larger interest; these are not of special interest but do not damage that of the structur within.

Original entrances remain, with 336 spans bridged by cantilevers and a complex central beam, nine feet deep. Concrete roof of braced ribs supporting rooflights.

Second floor board room, now Conference Room C, retains panelling installed' by the Design Research Unit. The other office spaces not of special interest, save for some original doors: these are identified by being varnished instead of painted.
