KPF, Beijing Institute of Architectural Design and Zhonghong Design:

The plan from KPF, Beijing Institute of Architectural Design and Zhonghong Design firm highlights renovation of Chaoyang Road and construction of four public squares

Under its design, Chaoyang Road, one of the main arterial roads in the area, would be changed into a street friendly to both pedestrians and motorists through the innovative solution of building an elevated pedestrian street 6 m above the existing road.

Four public squares are also proposed, among them the "Beijing Arena", a comprehensive facility including a museum, a library, hotels, shops and office buildings, and "CBD East Square", which would be home to a number of new city landmarks to symbolize the east gate of Beijing.

Also one of the world's top design firms, KPF's iconic building designs include the World Bank and IBM headquarters. Its partner Beijing Institute of Architectural Design designed the Great Hall of the People, the National Museum and Terminal 3 of Beijing Capital International Airport.

China Academy of Urban Planning and Design and Space Syntax:

The proposal by China Academy of Urban Planning and Design and Space Syntax would change CBD's skyline with design of new landmarks, including one called the "Tower of Life". The plan also projects building an 8-hectare central park and office buildings tailor-made for small and medium-sized businesses.

To minimize impacts from additional traffic, the plan suggests adding three subway stations - a branch to Line 7, a line to link the airport and an extension from Line 1.

China Academy of Urban Planning and Design is one of the top design companies in China, while Space Syntax is based in London.
