Polhemus & Coffin

Together they contributed to a joint publication, Small French Buildings: The Architecture of Town and Country,[1] with 183 plates of sketches, illustrations and photos, published by Charles Scribner & Sons in 1921.

Their modest French country manor "Mille Fleurs", designed for Mrs Daniel Guggenheim on the Gould-Guggenheim estate in Port Washington, New York, on the Gold Coast of Long Island, was completed in 1932; it is modeled on the vineyard Château Beauregard, Pommerol.

Designed for Lucy Drexel Dalgren in 1929, at one time Champ Soleil was the residence of Russell Aitken, artist, big game hunter, Associate Editor of Field & Stream Magazine and step-father of Sunny von Bülow.

Coffin expressed an affinity and passion for French country structures, and the firm designed many single dwelling homes in New Jersey, New York, and Connecticut.

Coffin also designed a few homes in Onteora Park Historic District, the former artist community and long-time summer retreat outside Tannersville in upstate New York.
