The layout of the complex, proposed by CENTRAL OFAAU, is structured around two distinct volumes: one for the logistical needs of musicians and technical staff, and the other for the audience. Between the two buildings lies the concert hall, an acoustically isolated space of 382 m² with a capacity of approximately 500 people, complemented by a rooftop terrace.
With a surface area of nearly 900 m², the building is designed with a structure capable of adapting to changing uses over time. Its construction system distinguishes between a permanent base—made of concrete—and a series of removable elements, such as enclosures, finishes, and equipment, which allow for flexible and reversible reorganization of the spaces. In this regard, it pays particular attention to the principles of circularity, adaptability, flexibility and minimisation of the carbon footprint, especially in the choice of materials.

Project description by CENTRAL OFAAU
A mythical venue for underground culture for more than 25 years, Magasin 4 is settling along the Brussels canal. A cultural and evolving infrastructure, this new temple dedicated to music and celebration has doubled its spatial and structural potential. From time one, the architecture offers a surplus of space to increase the planned activities. In the long term, the oversized load-bearing structure allows for the addition of different floors on the building and on either side of it. MAGASIN 4 is a public architecture celebrating Brussels' initiatives, energy and otherness, opening up the place to other possible futures. A hardcore structure with soft additions shouting out: NO FUTURE? FUTURE PROOF!
