The house sits on a one-acre (4,000 m²) block of New Bedford, between County, Madison, Joli Gonsalves and Seventh streets, in the middle of the County Street Historic District, where its wealthy citizens built their mansions in the 19th century.
It is a three-by-five-bay two-story yellow building with a front porch and balustraded balcony on either end and several tall chimneys emerging from the roof.
Inside, many of the original mahogany doors and their walnut veneers remain.
The cornerblocks and baseboards have elliptical echinus profiles of the kind commonly found in many Greek Revival interiors.
The window muntins have a beaded knife blade profile and the plaster ceiling cornices and medallions also have finely carved ornamentation.

A circular driveway leads up to the house, set back a mere 40 feet (12 m) from the street to allow for outbuildings and the property's garden.
It includes elements of all three of its periods of private ownership: a formal boxwood rose parterre garden with tall calla lilies, boxwood specimen garden, cutting garden and Woodland Walk surrounding a 19th-century wooden latticework pergola.
