The adaptive reuse and restoration of the Rivièrahal at Diergaarde Blijdorp in Rotterdam has entered a new phase with the selection of two design consortia. Led by Mecanoo, a multidisciplinary team will develop an integrated concept for the building’s future use. In parallel, a team led by BiermanHenket will focus on the restoration of the Victoriaserre. Both teams will work in close collaboration.
The Rivièrahal, designed by Sybold van Ravesteyn and completed in 1940, is the largest of the zoo’s twenty-one listed monuments, spanning over 6,000 square metres. The complex was originally organised into three parts: animal enclosures for great apes and large mammals, a central events hall with restaurant and stage, and the Victoriaserre greenhouse with its iconic water lily pond.
The central hall played a significant role in Rotterdam’s cultural life in the decades following the war, serving as the city’s primary venue for large gatherings. Generations of Rotterdammers recall concerts, events, conferences and dances held within its walls. Since 2014, the space has been in use as an indoor playground.
Years of intensive use have left their mark, and the Rivièrahal is now set for a new chapter that honours its architectural quality, rich history and significance for the city. Together with the selected partners, the design teams will explore how the building can expand its role within the city, potentially becoming accessible beyond the boundaries of the zoo.
Construction is expected to begin in 2027. Due to the scale and complexity of the project, and the risks for a non-profit organisation such as Diergaarde Blijdorp, the work will be carried out in phases, starting with the Victoriaserre greenhouse.
The restoration and adaptive reuse are supported by a contribution of €18 million from the Municipality of Rotterdam. Additional funding will be required in the coming years to realise the full ambition of the project.
