The mill cottage on the Lion Gardiner farm at 36 James Lane on the landmarked East Hampton Village green has become a museum displaying 19th and early-20th-century landscape paintings.

It is a contributing structure on the NRHP East Hampton Village District, replacing the original cottage on the lot situated with the windmill and Rev James historic marker.

In December 2014, the village signed off on an agreement to build a replica saltbox style colonial era home and took sole responsibility for a museum.

Terry Wallace, owner of the East Hampton Wallace Gallery had agreed to partly donate some of his collection of landscape paintings of the Hamptons (some dating to 1865), while the rest would be acquired by a sizable endowment to the museum funded by the Robert David Lion Gardiner Foundation.

Dominy made this extra effort partly due to this being the first of a kind, a new model windmill which was crafted to run two sets of millstones instead of one, and also because he built it for his major patron, John Lyon Gardiner.
