The Richardson House, as it was originally known—after its first owner and builder, Richard Richardson—[7] is North America's preeminent example of period English Regency architecture.

The house is notable for its early cast iron side veranda with elaborate acanthus scroll supports on which the Marquis de Lafayette addressed the citizens of Savannah on his visit in 1825.

During a renovation of the carriage house in the 1990s, the owners of the site discovered one of the oldest and best preserved urban slave quarters in the American South.

[12] The Owens–Thomas House collection contains furnishings and decorative arts from the English Regency period; containing effects of the Owens family, most pieces dating from the years 1790 to 1840.

[13] Collections include English Georgian and American Federal period furniture, early Savannah textiles, silver, Chinese Export porcelain, and 18th- and 19th-century art.
