Claim: Manchester One, at 260 feet, was one of Manchester's tallest buildings when completed but is now dwarfed by the CIS and Beetham Towers.
Evidence: At 80 m (260 ft), it is the joint eighth-tallest building in Manchester alongside the Manchester Civil Justice Centre. The tower was one of the first high-rise buildings built in the 1960s and 1970s in the United Kingdom. It is now dwarfed by the CIS and Beetham Towers. Manchester One, formerly known as Portland Tower and previously St. Andrew's House, is a high-rise building in Manchester, England, owned by Bruntwood and let out as office space. It was one of Manchester's tallest buildings when completed, and has since been renovated as part of Manchester city centre's regeneration.
