The Business Building Association Rallye was founded by Pascal Spitaels & Thierry Damsten 11 years ago. The purpose of the association was to bring together players from the real estate and construction sectors in Belgium. Throughout the year, a series of events take place in emblematic or unusual locations: the Queen Elisabeth Music Chapel in Waterloo, the Cinquantenaire roof in Brussels, the Tour & Taxis Maritime Station, URBEX sites in Charleroi or even the aquaponics farm in Anderlecht.
