The 112-year-old business is set in a building in the city’s French Quarter, and all the expansion was done in line with historic building regulations. The premises now includes two new gallery floors and two new outdoor garden spaces.
Changes will be unveiled at a special event on November 15.
MS Rau offers antiques, fine art and jewellery. It is run by third-generation owner Bill Rau, who selects each of the acquisitions.
