The stadium, VTB Arena Park, is designed by Dutch architect Erick van Egeraat and his Russian partner Mikhail Posokhin. Their plans include building a park with public green space, shopping, restaurants, training facilities, and even a hotel. The big design move here is the redevelopment of the Dynamo Moscow Stadium, a football arena and erstwhile Olympics venue built in 1928. With the new setup, two stadia will be plunked down over the old one, so that the existing perimeter facade is neatly preserved.
