 In April 2010 the 1878 engineer's office was substantially damaged by fire and, after a no prudent and feasible argument was made, approval was given for its remains to be demolished.It stood at the southernmost end of the complex on Lennox Street and comprised two adjacent single-storey, timber-framed structures, the former office on Lennox Street and a kitchen building to the rear.Clad in weatherboards, both parts stood on concrete stumps with timber slats between them.
