103-111 Gloucester Street is a part of the 'Long's Lane Precinct'. Long's Lane is a cluster of nineteenth and early-twentieth houses, rear yards, and laneways between Gloucester and Cumberland Streets, the Rocks. 103-111 Gloucester Street is a very fine example of a Greek Revival terrace row. While relatively common in Sydney in mid-nineteenth century, extant examples of this style in Sydney are now very rare: Fitzroy Terrace, Redfern is the only other example known.
The planning of the terrace emphasises the street façade incorporating a 'break front', a diminished central pediment, and raised entrance stairs originally with an awning.
