Following acquisition of the land by Frederick Unwin, it was leased to Michael Gannon, a former convict, who constructed a building on it, and a hotel (the New York Hotel) on the corner site next door, around 1840. Gannon's buildings were demolished in 1890 and replaced by the present buildings; the current shop at 93 George St, and a new hotel building at 91 George St (the ASN Hotel).
No 93 has been continuously occupied and used for commercial purposes since then. It was among the early properties to be conserved by the Sydney Cove Redevelopment Authority, following the Green Bans of the early 1970s.
