Montagne du Parc

Brussels, Belgium

200 years after a bank was founded, an architectural statement has been created on the same site. The design aims for a comprehensive upgrade in terms of aesthetics, sustainability and corporate culture. The careful, floor-by-floor disassembly of the predecessor buildings with its characteristic base and two towers saves valuable resources thanks to material separation and recycling.

Montagne du Parc is a highly flexible building: the standard floors can be divided into independently usable areas. Although commissioned as a bank headquarters, the building allows for a variety of uses. Arcades, yards and an elevator connecting the two city levels are open to the public. The first floor, following the street level, cpmprising two levels, provides space for stores, restaurants and public uses.

The use of the existing underground volume as seasonal storage contributes significantly to highly efficient operation and high comfort. The building's roof, with its flowing form, is a green landscape, largely free of technical attachments and a habitat for bees, birds and a wide variety of plants. Montagne du Parc offers even more green space in the courtyards and around the building.
