When the General Hospital was completed in 1816 the southern wing was used for its planned purpose as the quarters for the Assistant Surgeon as well as a storage facility. However, from 1823 the 39th Regiment, and briefly the 57th Regiment, used some of the rooms as hospital wards. The staff office (including "clerical offices and a medical depot") for the Military occupied the southern wing until 1854. From 1836, the Store Master also lived there, sharing the upper rooms with the Assistant Surgeon.
