The original building (now the administrations block) has a long history, having been granted by Governor Evans to a Rooty Hill station master, Captain Minchin, in the 1880s.

In 1936, the building, dubbed "Fairholme", began use as a guest house, eventually becoming a golf clubhouse before being purchased by the Epileptic Society and, later, the Franciscan Missionaries of Mary.
