Lustron houses were a post-war pre-fab solution to the housing shortage. They were advertised as having less maintenance due to the fact that nearly the whole thing was made of metal (inside and out). There were three models to choose from and this one, the Westchester, was the most popular. All the house parts would arrive as a kit—image 4 is of all the components laid out, which the order muppet in me just loves. The zig-zag drain spout near the front door is one of the uniquely-Lustron features, as are the square exterior panels.

This house is the only Lustron in Boston (though there is also one in Brookline) and was built by Vern M. Oech in 1948, who sold it to Robert and Helen Hardy shortly after. It was damaged by a fire in September of 2018 and as of the latest Google Maps shot in July 2019, it remains boarded up.

I was inspired to read about Lustron houses earlier this month after @sarahmarsom posted her v. cute mini-quilt of one.
