ZIN is a multifunctional project of about 110,000 m² above ground, 75,000 m² of which is office space (including a space devoted to coworking), 14,000 m² of housing, 16,000 m² of hotel accommodation, and leisure areas, hospitality and shops. 

ZIN will be fully integrated into its urban ecosystem and will be open to the city. It is a highly innovative project as much for its architecture as for its design and respect for the environment, notably in terms of energy near-neutrality and circularity. 

In 2018 Befimmo applied for the permit for ZIN, the redevelopment of the site of WTC 1 and 2. The first phase of the works, the demolition, has begun in the first quarter of 2019. The second phase should start in mid-2020 after the necessary permits have been obtained. The works will continue until mid-2023.  

The total construction cost of the project is estimated at €375 million. 

The 70,000 m² offices of the ZIN project are already fully pre-let to the Flemish authorities. For more information, please consult the press release of 12 March 2019: https://bit.ly/2EVGz5Z
