The building was designed by Petronas Towers architect César Pelli and features Moravian architectural themes, which are widely found in Winston-Salem. Notable aspects include the Moravian arch, which was used in the dome's design, and the Moravian star, which was used on the lobby's mosaics. Pelli said the tower design resembled a rosebud about to bloom. It is sheathed in Olympia white granite and is the only granite-domed skyscraper in the world. The granite comes from a single quarry in Sardinia. The dome rises 59 ft (18 m) and houses mechanical equipment. The gardens around the site were designed by Cesar Pelli's wife Diana Balmori, a landscape architect. Atlanta based developer Taylor & Mathis, managed the development.
