Mixed-Use Tall Building Design Competition

HOK designed this 64-story tower in the heart of Changsha’s River Delta District as part of a design competition for a confidential client. The building offers breathtaking views of the Xiang Jiang and Liuyang Rivers and is near one of Changsha’s primary transportation hubs.

Changsha is one of China’s “Star Cities,” which means the government has designated it as a hub for science and technology. It’s surrounded by stunning mountain and water landscapes.

Taking cues from the nearby mountain peaks, HOK’s design creates clusters of high-rise buildings of varying heights to present a unified appearance from a distance. The main tower’s interlocking forms taper toward the top, mimicking the tectonic beauty of the nearby mountains.

The tower offers Class A office space, high-end private residences and a luxury clubhouse perched atop its peak. Inspired by the ancient legend of the “Tian-Xin (Sky-Heart) Pavilion,” this space offers panoramic views of both the old city and the breathtaking natural environment. The restaurants and multifunction halls ensure that the clubhouse will be a hub of activity.

Sustainability was a key consideration. The results of the team’s solar analysis informed the building facade design. Careful attention was paid to the positioning of the building fins to limit heat gain and lower energy use.

The tower is a true representation of Changsha’s status as a “Star City.”
