CambridgeHOK is a horticultural engineering contractor with four divisions: glasshouses and greenhouses, vertical farming, horticultural construction, and energy. The company says it works from a headquarters and manufacturing facility in East Yorkshire on UK and international projects, with in-house design, structural and mechanical engineering, computer control, electrical, fabrication and installation teams.

It says it devised its first vertical farming system in 2011 and has since designed and built 10 commercial-scale vertical farms. Projects on its site include a 4.7 hectare glasshouse extension for Dyson Farming and climate controls at the Eden Project, and it reports being chosen to build research glasshouses at Kew Wakehurst. Since 2021 it has been part of Atrium Agri, a group of horticultural engineering companies.
