The project is transforming the Centre Monnaie building. It is reducing the amount of space allocated to offices and creating 120 apartments, a 316-room hotel and a facility for community or public service use. Two additional floors are being added. The base and basements are also being partially modified. The project pursues a cross-cutting environmental and energy approach (BREEAM Outstanding/WELL Platinum/NZEB).

Circularity ensured through flexibility and reuse

The project is designed to allow for adaptability, scalability, flexibility and future deconstruction of the building, while creating a new connection with the neighbourhood. The circularity strategy is based in particular on the massive conservation of the existing structure, the flexibility of the fittings and the design of the new structures (high-rise/open plan/strategic positioning of circulation and technical passages).

Decarbonised energy concept

The ambition is to achieve the ‘Carbon Hero – A label’ (One Click LCA benchmark), a carbon approach focused on decarbonised materials and techniques. The principles? Preserving more than 80% of the building's elements, recovering reusable elements and integrating them into the project (>4% of total inputs), recycling 90% of demolition waste, and installing carbon-neutral heating and cooling systems.

The transformation of this modernist office tower (1969) in the centre of Brussels aims to convert it from a single-purpose office building into a mixed-use programme with public added value. The ambitions for the MULTI project are:

To realise a contemporary and relevant project through thorough research into its spatial and social context. Understanding the current role and potential of the building has led to a number of proposals. As an Urban Platform, the project can serve as a connector between the various surrounding neighbourhoods.

The de Brouckère building is an exponent of Bruxellisation, the result of speculative work in the 1960s , driven by the desire to radically modernise the urban fabric without taking into account the existing buildings and other urban context. Research into the current performance and potential of the existing building in terms of sustainability and transformability has led to the realisation of a high-performance urban project.

As an Urban Platform and Urban Connector, the project aims to support and strengthen the creation of the pedestrian zone. This can be achieved by making the building as accessible as possible to the public, by updating a number of special places and potentials (including urban terraces and urban gardens) and by maximising the outdoor space around the building as a valuable space with a public character.

In order to achieve a socially relevant project that responds to current urban urgencies, the team wants to propose an emblematic approach. Transparent dialogue, design research, sustainability research (BREEAM) and reusability play a central role in this.

The Regent 47-48 project is a renovation of an existing building and will retain its original functional purpose. We believe that the renewed identity created by the new façade design will prove to be an asset to the urban landscape, both in terms of its aesthetic value and the reduction in energy consumption. In addition, a multipurpose space and a communal office space will be added to the building, along with three extra terraces in the courtyard garden and a renovated, greener terrace on the first floor, which together will ensure that the building and its use are open to the surrounding area. The hermetic office building will become a showcase for the new way of working.
