Nextensa obtained the urban planning permit for the Lake Side project on 2 April 2026, marking the final phase of the sustainable urban development of the Tour & Taxis site. The approval confirms that the project meets all requirements and represents a milestone in the development of the last zone. The granting of the permit follows a permitting process that began in March 2023.
After addressing the requirements formulated by two consultation committees, and taking into account the comments, concerns, and wishes of local residents and authorities, a new, revised application was submitted in December 2025. With Lake Side, Nextensa aims to further develop Tour & Taxis into a fully established sustainable urban district where living, working, and leisure come together. This new neighborhood will offer a mix of apartments, offices, retail, and hospitality.
In addition, new publicly accessible green areas will be created, along with more than 7,000 m² of public facilities. The project also includes 166 regulated (affordable) housing units. The commercialization and compliance monitoring of these units will be carried out in collaboration with the public operator citydev.brussels.
The Lake Side project represents a total investment of approximately EUR 555 million, spread over a period of about eight years. This long-term development allows for the phased realization of the different components of Lake Side. The project reinforces the existing character of Tour & Taxis and contributes to a vibrant, well-connected, and future-oriented neighborhood.
Sustainable energy supply (heating and cooling) will be ensured through a district-level geothermal installation. Starting from 2028, Proximus will gradually move into its new offices on the site.
