Mackay Estate Dairyman's Cottage

Mackay Estate Dairyman's Cottage is a two-story building with a brick base and wood frame upper section, topped by a steep flaring roof and rectangular windows with flat brackets. The structure sits on spacious grounds in East Hills and retains its original architectural features.

The cottage was built in 1902 by architects Warren and Wetmore as part of Clarence Mackay's Harbor Hill Estate. It gained recognition through its listing on the National Register of Historic Places in 1991, securing its place in the region's architectural record.

The cottage displays Japanese architectural influences in its deep overhanging eaves and window placement, reflecting how international design ideas shaped early 20th-century American homes. Visitors can see these elements today and understand how such foreign influences found their way into Long Island residences during this era.

The building sits in a quiet residential area and is easy to reach, where it stands alongside other original estate structures. Best visiting conditions occur during open hours, and checking ahead about access is recommended before planning a trip.

The cottage is one of only three structures remaining from the original Mackay estate, alongside the Gate Lodge and Water Tower. This rarity makes it a valuable window into the estate's history, as so little of the original complex survives today.
