Concourse at Landmark Center, Office complex in Sandy Springs, Georgia

The Concourse at Landmark Center is an office complex with two 34-story towers arranged around a lake within a 70-acre development in the Atlanta metropolitan area. The site includes more than 3,700 parking spaces across two nine-level parking decks to serve employees and visitors.

The complex was built in phases between 1984 and 1991 on 70 acres at the junction of Interstate 285 and Georgia 400. The two 34-story towers, Concourse Corporate Center V and VI, were completed in 1988 and 1991 to designs by Thompson, Ventulett, Stainback & Associates. An ownership group led by Atlanta-based Regent Partners took over the towers in late 2012.

The white lattice crowns of the towers are lit in changing colours: green in March for St. Patrick's Day, pink each spring for breast cancer awareness, purple after Prince's death in April 2016 and for World Prematurity Day in November 2021. In December 2017 blue and orange for Crohn's disease were mistaken by Georgia Bulldogs fans for Auburn colours.

The site sits at the northeastern corner of the Interstate 285 and Georgia 400 junction, so access is by car via those highways. Two nine-level parking decks hold more than 3,700 spaces. The grounds are spread over 70 acres around the lake, and the two towers stand east of Georgia 400, the king nearest the highway.

The towers' crowns are white lattice structures: the king's squared top sits on the east side of Georgia 400, the queen's rounded arcs immediately east of it. The colored lights on these crowns change for occasions, including purple for Prince after his death in April 2016 and pink each spring for breast cancer awareness.
