Former Drill Hall Now Royal Mail Sorting Office

This building began as a drill hall for the Royal Sussex Regiment, constructed between 1889 and 1890, and is now used as a Royal Mail sorting office. It was designed by Edmund Scott. The exterior is primarily stucco, possibly over stone, with a rear elevation of brown brick and a brick hall extending into Spring Gardens. The front range has a tile roof, while the rear has a slate roof.

The building is two storeys high with a basement and dormers, and it features an eleven-window front. A central, round-arched entrance has an elaborate surround of rusticated pilasters supporting an archivolt with a Gibbs surround. Above this are panelled pilasters with a triglyph frieze, a broken pediment featuring dolphins, a band of bay-leaf ornament, and a small segmental pediment. A round-arched entrance is also located in the westernmost bay, with a flat-arched works entrance to the east. The ground and first-floor windows are round-arched and lack architraves. Stone panels displaying the regimental arms are flanked by lions' heads at the east end. A moulded sill band runs below the first-floor windows, and the eaves have closely spaced brackets with simplified paterae between. Five pedimented dormers are present on the mansard roof, with six more recent dormers inserted in between.

The rear elevation consists of brown brick in English bond with gauged red brick heads to the first-floor windows. A long, single-storey hall runs parallel to Spring Gardens, also built in brown brick with a slate roof. New window openings have been made to the first floor. The interior of the building has not been inspected.
