The house is still surrounded by native trees, wide lawns and gardens, including peach trees where a large orchard once stood.
It was converted into a rest home by Ross and Bea Haywood in 1988. Cairnfield House changed hands in 1996, after which director Peter Beric extended the facility by adding three large residential wings to the old house.
Ms Bhana and Mr Baker bought Cairnfield in 2012. They said they fell in love with the property immediately and were impressed with the warm, friendly atmosphere between the staff, residents and families.
Some core staff members have worked at Cairnfield House Rest Home for 15 to 20 years, with one original staffer witnessing the growth from private home to rest home to hospital.
Ms Bhana said two open days would be held in June - one for the public and potential clients to have a look at what the facility offered, and one for health and welfare professionals.
