Schedule

The Gorlaeus Building will be constructed in three phases, with the new building due to be completed by 2028.

Phased construction

The structure of the building, with the central atrium and the wings placed perpendicularly to it, is highly suitable for construction in multiple phases. Phase 1 started in 2013 and was completed in 2017. Phase 2a spanned the period from 2017 to 2024.

Phase 2A

During Phase 2A, the central main axis has been completed, and the building has received three new side wings. Phase 2A provides accommodation for administration, various educational functions, 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, communal facilities have also been established, such as catering and a library. Additionally, a large new lecture hall for 180 students and two tiered halls for 100 students each have been added. Study associations have also been given a central shared space.

The central main axis of the building has been extended towards the Einsteinweg, where the new main entrance of the Gorlaeus Building is now located. To realize this phase, the LCP, the Chemical Storage, the Real Estate Expertise Center, and the Gorlaeus high-rise have been relocated. These buildings have been sustainably demolished.

Phase 3 (2025-2028)

The Gorlaeus Building will be completed by expanding on the side of the building where the LMUY building is situated. Currently, research is being conducted on the most sustainable way to proceed here, through the demolition or renovation of the LMUY building.
