Novartis Horsham Site Closure & Redevelopment

Horsham, West Sussex, UK · 2013-Present (closure announced 2013, redevelopment ongoing) · Not directly applicable for closure; multi-million pound investment for science park, significant for housing redevelopment.

The judgement call

Account-gated at launch

Novartis's decision to close its Horsham site in 2014, with the loss of hundreds of jobs, highlighted the vulnerability of pharmaceutical R&D and manufacturing to global corporate restructuring. - The subsequent redevelopment of the brownfield site for housing and a potential science park demonstrates a strategic effort to repurpose former industrial land for economic regeneration and community benefit. - The project underscores the challenges and opportunities in transitioning from a single-industry site to a mixed-use development, requiring careful planning and investment.

Key engineering challenges

Decommissioning a large pharmaceutical manufacturing and R&D site. - Remediating brownfield land for new uses (residential and commercial). - Designing and constructing new residential and commercial infrastructure on a former industrial site. - Integrating new developments with existing urban fabric and infrastructure.
