The land was subdivided in 1950 with Senior retaining the rear portion, and the Roderick Street frontage containing the house was transferred to Thomas Keith Johnson.

The name of the organisation was changed to the Society of Saint Vincent de Paul State Council of Queensland and the land was amalgamated and a new Certificate of Title issued in 1983.

A hostel for homeless men was built at the rear of the site c.1982, and operated as such until June 1994, since which time it has been used as a welfare office and drop-in centre.
