A building record was made in 2011, prior to demolition.

A single-storey rectangular structure with a pitched felt roof and vertically-boarded cladding to the walls. Access is via offcentre doorways in either short end and there are six large windows on both of the long sides. The south-western end of this building is taken up with a WC and urinals on each side of the entrance and a large open-plan office. To the north-east of this are two square offices and a rectangular office on either side of a corridor leading from the entrance at this end of the building. This structure does not appear on the 1875, 1897 or 1921 O.S. maps and is only present on the modern O.S. map; as such it is likely to date to the latter half of the 20th century.<1>
