Hexagon Tower was originally built in the 1970s and first occupied by Imperial Chemical Industries before being used by AstraZeneca and Avecia, prior to becoming a science park with its purchase by La Salle Investment Management in 2008. Since the acquisition LaSalle has invested £2m in modernising the facility.
The building is part of the national Business Environments for Science and Technology Network, the largest portfolio of privately owned science parks in the UK.
