About the project

The new building for the Faculty of Mathematics and Natural Sciences is a significant milestone for Leiden University and the faculty in particular. A new building is being realized in three phases. The first phase of the new building was put into use in 2016 and covers an area of 45,000m2. The second part, with an area of 30,000m2, was completed in 2024. From 2026 to 2028, the last phase will be realized. In 2028, the entire Gorlaeus Building will be ready, covering an area of almost 100,000m2.

From decentralised to centralised

The eight institutes of the faculty were previously housed in various buildings on the Leiden Bio Science Park. Because some of the buildings are outdated and have high energy consumption, the university is creating the new Gorlaeus Building, a high-tech environment with state-of-the-art research and educational facilities. A large part of the institutes and faculty services are now housed under one roof. The new building encourages interaction between researchers and students.
