The William Shay Double House is a residential duplex at Point Street and River Road in New Hamburg, New York, United States.

The duplex is a brick building in the Gothic Revival architectural style, unusual for both its scale and amount of decoration for utilitarian worker housing of the period in the area.

A steeply-pitched cross-gable runs from east to west; on both elevations it has trefoil detail in the peak and a single rounded-arch window with corbeled stops.

The roofline has a wooden cornice decorated with paired brackets and acorn pendants flanking frame panels all around.

[2] The alternation of panels and paired brackets in the roof, for instance, is identical to one shown in Villas and Cottages, an 1857 pattern book by Calvert Vaux.
