This building is a part of the complex built by the Sisters of Mercy to provide accommodation and a school.

Reverend Matthew Gibney, the Lord Bishop of Perth, laid the foundation stone of this building in July 1903.

[2] The construction of the convent was almost entirely funded by the family of Daniel Connor, who had been a very devout Catholic.

There are gabled wings to each end, with half timbering creating a symmetrical façade.

There is a two-storey panelled side extension joining the building to the current St John the Baptist Church.
