This huge office complex occupies an entire block between Avenue de la Porte de Hal/Hallepoortlaan, Rue de Mérode/de Mérodestraat and Rue de Russie/Ruslandstraat in Saint-Gilles/Sint-Gillis, close to Bruxelles-Midi/Brussel-Zuid station. Postmodernist in style, it was designed in 2002 by architect Jacques Baudon of A+U. It is owned by Belgian rail operator SNCB/NMBS and is currently home to its offices. The building has a total surface area of more than 48,000 m², spread over 15 levels, including 5,600 m² of multi-storey parking on three levels. The three façades form a right-angled triangle around a landscaped inner courtyard. The main entrance at number 40, Avenue de la Porte de Hal/Hallepoortlaan features a cylindrical glass bay set into the building. The two façades forming a right angle between Rue de Mérode/de Mérodestraat and Rue de Russie/Ruslandstraat are covered with a semi-cylindrical zinc roof, and there is a rotunda-shaped bay at the corner. The superstructure of the columns and their metal reinforcements is left exposed, adding a hint of high-tech architecture.
