[1] In 1989-90, extensive rear additions were constructed to provide a mail room, bicycle/scooter shed, cleaner's store, post office box lobby, covered loading bay and plant enclosure.
Alterations at first floor level included construction of a small kitchenette in the former sitting room and installation of staff amenities in the western half of the plan.
The two storey brick structure with stucco mouldings is dominated by an octagonal tower with conical roof, onion dome and crescent moon finial.
[1] The rear service yard occupies the broad northern portion of the triangular site and crossovers from Wellington and Shields streets provide vehicular through access.
[1] The complex roofscape is variously composed of mansard and jerkinhead forms and clad with slate, however original cast iron cresting has been removed.
[1] Fenestration is regular between the long elevations and between floors, however openings are variously defined by alternative arch and tracery types according to hierarchy and each contains a timber-framed double-hung sash window.
[1] Externally, Flemington Post Office's ability to demonstrate its original design is very good with regard to the architectural conception, principal materials and detail despite rear additions constructed in 1989 and replacement of the private porch roof.
Architecturally, Flemington is an excellent solution to an awkward site, considered to be one of the most skilful compositions by the Public Works Department architects at the time.
[1] Flemington Post Office also has dramatic landmark qualities deriving from its prominent position on an acute-angled site, dual approach, visibility in the round, and a five level tower.
The highly artistic and skilful handling of an awkward triangular site demonstrates great merit and unity of conception, despite the hand of three separate designers.
Flemington Post office has social significance within this inner region of Melbourne, not just for its continuity of providing postal services from the site for almost 120 years, but also due to its much valued form and architectural treatment.
Flemington Post Office is additionally associated with three enduring and capable architects engaged by the Public Works Department during the late nineteenth century, JT Kelleher, AJ McDonald and JR Brown.
The eastern district of the architectural section of the Department was considered to be the most inventive and produced many notable and award-winning buildings with remarkable features, of which Flemington is one of the most distinguished.
