Liverpool property group Downing has completed a major fit-out for the UK Border Agency (UKBA) at its Capital building in the city.
The government department signed up for the space in 2009 and is now consolidating its six Liverpool offices, with 2,000 staff, at the Old Hall Street building.
The agency has nearly 222,000 sq ft of a total 390,000 sq ft. Other tenants include the city's economic development company Liverpool Vision, insurer Royal Sun Alliance and Tesco.
George Downing Construction, the group's construction arm, carried out the latest phase of works on the fourth, fifth and sixth floors covering a total of 88,000 sq ft.
John Clegg, head of property management at Downing, said: "The Capital has been transformed under our ownership and is a real benchmark for highest quality, refurbished space across the region.
"Apart from the sheer scale of the project, the works were particularly complex with unique operational requirements. It's testament to our in-house projects and management teams that despite works being undertaken around existing tenants, disruption was kept to a bare minimum and clients remained happy throughout our activity."
