UNStudio: Le Toison d’Or

For this residential and retail complex in Brussels UNStudio brokes up the facade by means of variations in texture, depth and rhythm, investigating the space between the abstract and the figurative, to create moments of tacit allusion to the pictorial.

Designed by UNStudio for ProWinko and in collaboration with Belgian architects Jaspers-Eyers, Le Toison d’Or is a hybridisation of a traditional building-block typology and a mixed-use development with a retail podium.

Located on the Avenue de la Toison d’Or between two historical gates (the Porte Louise and the Port de Namur), the mixed-use complex integrates into the urban fabric of its surroundings, whilst simultaneously merging a retail and residential programme.

In order to avoid the monolithic qualities common to block structures, the facade is broken up by means of variations in texture, depth and the repeating rhythm of a series of curved vertical frames. These frames serve to enclose the balconies of the apartments on the upper floors, whilst also facilitating the large display windows of the retail units. In contrast to the vertical articulation of the street facade, the facades surrounding the elevated courtyard garden follow a horizontal arrangement. Here generously proportioned balconies provide a more tranquil experience of city life. To access the apartments visitors and residents enter the building from the street side, where a large sculptural staircase leads them up to the main reception lobby, which is located towards the rear and elevated above the two retail levels. From here they can continue to further lobby areas furnished with informal seating, where the elevators to the apartments are also located. The apartments in Le Toison d’Or vary in size from small to large, enabling a varied demographic of city residents.
