Despite its diminutive size, this one-story orange brick, gable-roofed building has a distinguished presence on the street. Harm Jan Huidekoper and his sons bought the Holland Land Company's regional holdings and conducted their public business in this small space. (Huidekoper worked for the company from 1805 to 1836.) The building appears to have been a dependency of the large Huidekoper House (demolished) next door. There is evidence in the brickwork of some alteration to the facade of the building. As it is today, there is a round-arched window in the gable end and a segmental-arched portico sheltering a fanlight over the entrance door. The building has been in continuous use as various offices and is now a museum.
