While Terang and Sorrento post offices, along with that at Woodend, have been thought by some to have been the first Commonwealth designed and built post offices in Victoria, original plans in the National Archives of Australia suggest that Terang and Sorrento, and following from that Woodend, were constructed by the Victorian Public Works Department under its architect, John Hudson Marsden.

[1] Alterations c. 1920s-1940s included rear additions; construction of additional rooms to west, incorporating new entry; removal of verandah return to this elevation; alterations to facade including bricking in of original entry and adjoining window; internal reconfigurations, expansion and formation of new mail room, introduction of post office boxes to facade and east elevations.

[1] The Sorrento post office is a one-storey building in the Federation style and includes a postmasters quarters attached at the rear.

The roof is of corrugated iron, which extends into a verandah over the footpath which is supported on heavy timber stop-chamfered posts accentuated by decorative brackets, with simple frieze work above.

The face of the gable above the verandah is stuccoed, containing the words "Post and Telegraph Office" in a late nineteenth century Arts and Crafts calligraphy.

The post office is set within the context of a number of historic buildings in the Ocean Beach Road streetscape, Sorrento's main shopping precinct.

[1] The former residential component in timber has been heavily altered, and the original rear section has been concealed by a weatherboard extension, running east to west across the building.
