Built in 1900 for Herbert and Martha Blow Wadsworth as a winter residence, the building was completed under the name of Wadsworth House. Herbert Wadsworth was the grandson of James Wadsworth (of Geneseo). Martha Blow Wadsworth was from St. Louis, Missouri and a descendant of Henry Taylor Blow. In 1918 the Wadsworths donated the mansion to the Red Cross, who sold it to Mabel Thorp Boardman and a group of women in 1932, for $125,000. The women renamed it the Sulgrave Club, a club intended for music, art and social gatherings. The new club's name came from Sulgrave, the civil parish in Northamptonshire, England that had been the ancestral family home of George Washington.
The Sulgrave Club was designed by Frederick H. Brooke in a Beaux-Arts design from the 18th century. It is one of Washington’s first mansions to follow this style of architecture. The house was built of yellow Roman brick and cream terra cotta.
