The business park, which already employs 200 people, will welcome cardboard tube manufacturer J Stell & Sons Ltd, which has expanded from its existing site in Keighley to the largest unit at Riverside, covering 90,000 sq ft.
Other premises have been taken by Keighley-based bathroom and kitchen equipment distributor Cavalier Marketing, Ilkley-headquartered engineers Spooner Industries, Bingley-based Dowsons Food Machinery; and Keighley-headquartered Advanced Couplings.
Addingham-based Turner Developments took on the role of designing, building and selling the new units, which span over 270,000 sq ft of the 9 acre Keighley site.
James Turner, managing director at Turner Developments, said: “The success of Aireside showed very strong demand for prime industrial property in the area, where the many attractions include great access to the Aire Valley trunk road.
“Unprecedented interest in phase one allowed us to fast-track our plans at Riverside Business Park, and now we have reached the conclusion of what has been a hugely successful project for the Aire Valley.”
