Extending the tower to 100 meters, Wiel Arets Architects' (WAA) design for Antwerp Tower will make it the third tallest building in Antwerp and hopes to provide a hub of activity to an already vibrant part of the city. The residential tower will contain 6 to 14 apartment units on each floor, each with their own loggia, ranging in area from 40 to 120 square meters and penthouses that will be up to 240 square meters. The system of load bearing walls and columns partially replacing the existing structure will minimise the need for columns within the residential spaces.
