He became president of the board of trustees of the Metropolitan Museum of Art, and founded the Hearth and Home Corporation to provide housing in downtown Manhattan, New York City.

[5][6] Sloane was heavily involved in manufacturing and selling this style, and had another subsidiary, the Oneidacraft Company in Oneida, New York, which made it as well.

In 1920, Hearth and Home purchased the entire block of mid-19th century row houses bounded by MacDougal, Sullivan, West Houston and Bleecker Streets and renovated those on MacDougal and Sullivan into spacious apartments, with the backyards of the buildings connected to form a common garden.

The New York Times said about the project on January 30, 1921, that "[Coffin's] development made a real contribution to the solution of the housing problem and is an excellent example of what can be done to other properties in the city, and the rehabilitation of homey old buildings."

The buildings were sold to individual owners in 1924, but with covenants guaranteeing aesthetic continuity and no future redevelopment of the site.
