Please be aware that a building with a reception is accessible when open. However, some buildings are not freely accessible as they do not have a reception. Additionally, the Helix building is currently restricted and can only be accessed with campus card authorization due to safety concerns related to its numerous labs. Starting from late 2025, staff and students will be able to access the public areas, but visitors will still be restricted. Furthermore, please note that a decision regarding how to request access outside of office hours is still pending. We will provide further clarification once a decision has been made.
Please note that these opening hours will take effect as of January 1st, 2025.
