The canned fish brand has moved into more than 10,000 sq ft of office space at No. 1 Mann Island after Warrington-based interior group, Claremont, completed a design and fit-out.
The company has taken one floor at the 13-storey building, which now houses 70 of its staff, on a 15-year lease.
The office includes a reception, board and meeting rooms, a tasting kitchen with product display area, departmental offices, open plan office space, breakout areas and a staff kitchen.
John Glennon, group IT director at John West said: "We were looking for the best partner to design and deliver an iconic water-front head-office that reflected our brand and personality.
"The end result is fantastic. Our staff love their new environment and the many new ways and places to work. We're now proud to welcome VIP guests from our group, suppliers and customers – something we avoided at our prior location."
Ann Clarke, joint managing director of Claremont Group Interiors, said: "This projects is proof that companies are still growing and prospering even in tough economic times. The client needed more space to accommodate growth and to better reflect their brands and the work we've delivered achieves that.
"For Claremont, these projects show our expertise at its best, drawing on the full range of in-house interior design, fit, furniture and AV capabilities."
Chris Hennessy, associate at Matthews & Goodman, brokered the deal on behalf of John West.
Mark Worthington, director at CBRE, acted on behalf of the landlord.
