An East Hills house, which once served as the dairyman's cottage on the Clarence Mackay estate, is now on the market for $1.769 million.

Built in the early 1900s and designed by Warren and Wetmore, the cottage was one of many outbuildings on the once-648-acre estate called Harbor Hill. The Mackay family made its fortune from the Comstock silver lode in Nevada and hosted parties for the Prince of Wales and aviator Charles Lindbergh, says Peter Crifo, a trustee on the board of the Roslyn Landmark Society.

The three-story cottage sat adjacent to the estate's cow pasture and pulled double duty as the dairyman's residence and a store selling milk from what is now the living room.

“It's a very distinctive-looking house,” says Maggie Keats, listing agent with Douglas Elliman Real Estate. The cottage can also claim the late lyricist Hal David as a former resident.

Original wide plank floors are throughout the 3,766-square-foot home, and the dairy's hayloft is now a bonus room. There are five bedrooms, three bathrooms and one half-bathroom. Other features include a formal dining room, an eat-in-kitchen, a fireplace and a covered veranda.
