Architecture studio Rogers Stirk Harbour + Partners has designed a terminal for an airport in Shenzhen, China, that will be arranged around a large covered garden. The 400,000 square-metre terminal will be an extension to Shenzhen Bao'an International Airport and is designed to handle 31 million visitors a year. The building will have a streamlined form with an undulating, sweeping roof that emulates the pattern of airflow. Airport will be built around central garden Rogers Stirk Harbour + Partners' terminal will include a central 10,000-square-metre garden that was designed to act as a "front door" to the city of Shenzhen. "The design concept has at its heart a 10,000 square-metre central garden space, the size of 40 tennis courts," said Rogers Stirk Harbour + Partners partner Andrew Tyley.
