Inside Unit 2, a very large Children's Preventorium at the former South Mountain Sanatorium, lies this unusual structure. Located on the fourth floor in the center section of the building, sits what resembles a standard family house, complete with a living room, dining room, bathroom, kitchen and two small bedrooms. Sadly, not much information can be found about this house, but from the documentation I have found, it seems it was designed to be a rehabilitation home for a family with a child who had tuberculosis, but was not yet showing the active symptoms of the disease.
