Houmas is actually two houses joined together under one roof: the original, 1775 four-room structure and the larger, Greek Revival–style house, completed in 1828 after 17 years of construction. The former sugar plantation has been restored several times since then, including by the current owner, who invested millions in turning it into a fabulous showcase inside and out, a popular event venue, and his home. It’s filled with stunning art and antiques and surrounded by elegant formal gardens. He also installed a lovely cafe, a pleasant bar, and a fine-dining restaurant amid these splendid environs, so one can make a day of it (or 2 days, if you stay in the fetching cottages, outfitted with antiques and modern amenities.). Note that the upscale restaurant is “event” dining, requiring reservations and proper dress (and a thick wallet).
