Architect William Landsberg (1915–2013) designed more than a dozen homes on Long Island, including his own in Port Washington, which just went on the market. Constructed in 1951, and expanded in 1961, this is the first time the Landsberg family home has been offered for sale.

Built into a hillside and surrounded by trees, the house celebrates and engages with its natural setting. The floor-to-ceiling windows make you feel like you’re in a treehouse, with beautiful views in all directions. There is a stream tumbling by, adding sound ambiance, and thanks to how the house is positioned on the hill, it’s very private.

The façade features a fieldstone wall made of “Manhattan Schist” – which came from the excavation of the New York City subway – and vertical wood cladding made of Georgia cypress. The single window above the garage is a Landsberg signature and can be found on two other houses he designed.

A graduate of Carnegie Institute of Technology and the Harvard University Graduate School of Design, Landsberg studied under and worked for Walter Gropius and Marcel Breuer. The influence of these two Bauhaus masters, especially that of Breuer, can be seen in this house.

Landsberg’s home has been featured in Architectural Record and is listed in the Docomomo US Register. In 2014, the state of New York included this property in its list of sites to be added to the State and National Registers of Historic Places.

Listed at $1,150,000 with Jill Berman of Douglas Elliman Real Estate. Her mobile: 516.375.9101.

I’m sorry to report that the furniture is not included with the sale.
