Connectimmo, Proximus' real estate subsidiary, approached Freestone to carry out condition assessments of the Proximus Towers in Brussels. The two office towers, each with 28 floors, date from 1988 and are no less than 335 feet tall. Furthermore, one of the towers has a 105-foot antenna, bringing its total height to 440 feet. The towers are connected to one another by walkways on the 25th and 26th floors.
