A clip from the 1936 "Guide to Better Homes," published by American Builder and available on the Internet Archive.
There's a single Kelvin Home in Albuquerque, New Mexico, and it's on the state's register of cultural landmarks. A Kelvin Home in the Cleveland Heights neighborhood of Cleveland, Ohio is the topic of a thorough history on the neighborhood's website.
But the metro Detroit area may be home to dozens of them. They were born here, after all: developed by the Detroit-based Kelvinator Corporation, a Kelvin Home was designed to demonstrate that "an air-conditioned home with automatic heat, automatic refrigerator and electric cooking range can be built on the owner's lot for less than $7,000," reported the Detroit Free Press in 1936 — and that included the builder's profits and the real estate agent's commissions.
The first Kelvin Homes in the Detroit area were built in 1936 in the neighborhood around the Kelvinator plant, better known today as the AMC Building, which Crain's reported this week will be demolished as part of a $66 million industrial redevelopment on the site. A quick tour of Google Street View shows that many of these model homes still exist, like this one on Strathmoor:
There are also a handful of Kelvin Homes in Livonia's Rosedale Gardens historic district. Some of those homes were sold furnished by the J.L. Hudson company, to further show off stylish living on a budget. If you spend any time in the Historical Detroit Area Architecture Facebook group, you may have seen other examples of Kelvin Homes designed by architect J. Ivan Dise in Royal Oak, Birmingham and the Grosse Pointes.
Kelvinator never intended to get into the home building business, but to prepare and sell its designs and specifications to other builders and architects (with Kelvinator-made AC systems and appliance baked in, one assumes). Still, the experiment faded away after the 1930s, due to lukewarm demand for them in the housing market.
