 The Alsop house was built in 1838–1839 by Richard Alsop IV for his twice-widowed mother, Mrs. Maria (Alsop) Dana.The short-lived architectural firm formed by Landra Beach Platt and Francis Benne who worked together in New Haven under the tutelage of Sidney Mason Stone was evidently responsible for the design, although it is possible that they drew their inspiration from Ithiel Town's own home in New Haven, which may account for the similarities of the two structures as well as for a former attribution of the Alsop House to Town himself.
