The St.Regis Residences are a luxury residential development in Southbrickell, Miami, consisting of a 48-story main tower (known as Astor Tower) that houses 149 two to seven-bedroom residences, including exclusive Penthouses and Sky Villas.

The building, designed by Robert A.M.Stern Architects with interiors of the Rockwell Group, offers high standards in every detail: European marble floors, ceilings up to 11 feet, private elevator and separate entrance hall in many units. The kitchens are Italian with natural stone countertops, the bathrooms have showers and spa tubs, and the spacious balconies or terraces look out onto the skyline, the bay and the ocean.

The tower is designed to offer a sophisticated living experience, integrating fluid spaces and high-level interiors.
