Serviced office provider Citibase has taken 7,500 sq ft on the top floor of the Exchange in St John's Street in Chester city centre for a rent in the region of £15/sq ft.
Andrew Duncan, director of Opus North, owner of the building, said: "The Exchange, which was previously occupied by British Telecom, is a superb mixed-use building. It has been comprehensively refurbished to create 25,000 sq ft of offices, retail units, restaurants and hotels. Tenants include Travelodge, Pizza Express and Pitcher & Piano.
"The Exchange is close to Chester's main retail and leisure facilities. In addition, Chester's main bus station is approximately half a mile away whilst Chester's mainline railway station is nearby, with regular services to Manchester, Liverpool and London Euston."
Opus North is based in Ilkley, west Yorkshire.
