The stories behind some of New Canaan, Connecticut’s treasure trove of modernist homes have been less than uplifting. In addition to Philip Johnson’s famous Glass House, the wealthy enclave boasts dozens of homes by Johnson and his colleagues known as the Harvard Five. An ongoing battle simmers between some of the town’s wealthy residents who favor sprawling McMansions and a passionate contingent of modern architecture fans. At least 20 of the homes, built in the 1940s, ’50s and ’60s–have been torn down, usually to build larger houses on the property. One embattled example is a lesser-known Johnson house known as the Alice Ball House. The 1,700-square-foot home, built in 1953, has been referred to as a “livable version of the Glass House.” And it’s now for sale for $7.7 million–along with approved plans by the current owner, an architect who has envisioned a companion property on a much grander scale, including an indoor pool and a massive skylit underground garage.
