An audacious architectural proposition to the city offers a newfound visibility to the former “Palais des Congrès” by means of a poetic emblem embodied in the glass cube that forms the principal entry to SQUARE, Brussels Meeting Centre.

Its treelike structure and an aesthetic based on transparency and light, irresistibly evokes landscape architecture, takes root in history and projects the « Mont des Arts » into modernity. This monumentality, mild and poetic, dialogs with the image of the garden. Present and at the same time melting into the surrounding architectural landscape, it changes in materiality as the light and time of day change. The entry, in the form of a large exterior auditorium, allows an entry to the base of the cube, sliding along the exposition hall under René Pechère’s renovated historic garden. A terrace leads to the upper access situated on the « Esplanade du Mont des Arts ».


The carefully articulated cube contains ribbon shaped suspended stairs and catwalks that connect the different access levels to the complex of 50,000 sqm that optimally exploits the complex existing structure and succeeds in the challenge of increasing the capacity and the efficiency of the whole. Square now offers 27 meeting rooms of 40 to 1,200 for a total capacity of 3,538, an exposition zone of 3,670 sqm divisible in two distinct entities with a free ceiling height of 6m, a restaurant, and a « brasserie » of 420 places.


The reorganization fully exploits natural light in a building where the majority of spaces are underground. The meeting centre also benefits from the presence of prestigious works of art that decorate the foyers and position colours, which create an ambiance specific to the site.

Square therefore constitutes an attractive technological jewel at the heart of the « Quartier des Arts » and consumes the transformation of an important historic site by respect for it’s history and ambition for it’s future.

The poetic emblem of the cube becomes the urban symbol of a new site of communication with the world.

    instruments of a building should take into account environmental conditions.

    Very elegant, and surprisingly balanced in regards to the intricate curtain wall. I’m a big fan of its lightness, its transparency to reinstate the context of the older buildings, and the proportion just seems on key. Very well composed piece of work.

    happy to see at last a building from belgium. I live in brussel since 13 years, i know very well this place where there was a lot of try to do something and i find that they finnally done sommething very nice (not so easy because of the rest of the place). Thanks to A2RC for this (too uncommon in belgium) piece of architecture.

    The contrived curtainwall complexity is annoying and distracts from what otherwise seems to be a clean composition with a nice entry sequence.
