This cutting-edge office building, with laboratory facilities, is situated in the Leiden Bio Science Park. Through innovative and sustainable design, we have established the new benchmark for 21st-century workspaces.
By revitalizing the ground floor with a blend of work-related functions, this building transcends the traditional office concept. It becomes a dynamic hybrid space that fosters innovation and encourages collaboration.

A new home for Janssen
We developed a new building for Janssen Biologics B.V. and Janssen Vaccines & Prevention B.V., part of the Janssen Pharmaceutical Companies of Johnson & Johnson. The Leiden Bio Science Park was already home to Janssen, and with this new building Janssen expands its offices on the park.
Health, safety, collaboration and transparency are key principles for the new office building with laboratory facilities. The design has an efficient and flexible layout to optimally support the various departments of the tenant, with innovation and collaboration as the most important spearheads. The spacious future-proof workspaces are surrounded by building-related facilities such as a spacious and bright atrium, a roof garden and a full company restaurant.
If you have specific questions about this project, please reach out.


“By activating the ground floor with a mix of work-related functions, this became more than just an office building: it is a hybrid building for work, which stimulates collaboration and innovation.”
