Expansion of Johnson & Johnson at Leiden Bio Science Park

Leiden University has transferred land on a long-term lease to Janssen Biologics, a subsidiary of Johnson & Johnson, for the construction of a new facility at the Leiden Bio Science Park. The company is expanding its operations with additional laboratories and office spaces next to its existing production site along the A44.

“Johnson & Johnson and Leiden University are partners, both located at the Leiden Bio Science Park (LBSP), so we are pleased to make this land available,” said Joek Kruiderink, project director for Area Development at Leiden University Real Estate. “Collaboration with companies at LBSP is important for the university. We focus on supporting the growth of established companies, as this can enhance our partnerships.”

The company is involved in various sectors at LBSP, including pharmaceuticals and medical technology. In 2023, J&J Innovative Medicine, Biologics opened a new facility on university land at Emmy Noetherweg. The latest investment in the Optima building will add more space for laboratories and offices to support production growth and innovation.

The new building will be connected to the existing structures on Einsteinweg via a bridge, creating a cohesive complex. The new facility will cover 7,000 square meters and consist of three floors.

For over three decades, the university has been working with the municipalities of Leiden and Oegstgeest to develop the Leiden Bio Science Park, with a focus on advancing public health through research and innovation in life sciences and health. While the park is primarily intended as an industrial area, the university envisions it as a growing urban district with residential areas, parks, restaurants, shops, and the Faculty of Mathematics and Natural Sciences campus. This development will continue over the coming years.

Construction of the new Johnson & Johnson facility is expected to begin in early 2026.
