The Gorlaeus Building will be constructed in three phases, with the new building due to be completed by 2026.
The building’s design, with its central atrium and the side wings leading off from that area, is well suited to construction in multiple phases. Phase 1 began in 2013 and was completed in 2016. Phase 2 of the new building is divided into phase 2A (2017 – 2023) and phase 2B (2023 – 2026). Splitting construction into multiple phases means that teaching and research can continue unimpeded while construction is ongoing.
During Phase 2A, the central corridor will be completed and the building will gain three new side wings. Phase 2A provides housing for the Faculty Board and supporting staff, a range of educational rooms and five institutes: Mathematical Institute (MI), Leiden Institute of Chemistry (LIC), Leiden Academic Centre for Drug Research (LACDR), Leiden Institute of Advanced Computer Science (LIACS) and the Observatory.
In this phase, the communal facilities are also realized, such as catering facilities and the library. In addition, there will be a large new lecture hall for 180 students and two ascending halls for 100 students. Study associations will also share a central space.
The building’s central main axis leads towards the Einsteinweg, where the new main entrance to the Gorlaeus Building will be located. The LCP, Chemical Storage, the Real Estate Expertise Centre and the Gorlaeus high-rise building will have to make way for the construction work during this phase. These buildings have been – or are due to be – sustainably demolished.
Schedule: Phase 2A
Design 2017 – 2019
Implementation and completion 2020 – 2022
Ready for use 2023
Phase 2B will extend the Gorlaeus Building with an extra wing that will house functions such as offices and laboratories. The final stage, phase 2B, will provide accommodation for the Leiden Institute of Physics (LION). The schedule for this phase is:
Design 2023 – 2024
Implementation and completion 2024 – 2025
Ready for use 2026
