The Government Property Agency has exchanged contracts to acquire five acres of the former Central Retail Park in Ancoats, from Manchester City Council.
The land purchase is expected to complete fully next year, with construction of the 800,000 sq ft Government office complex set to begin in 2026.
Parliamentary Secretary for the Cabinet Office, Alex Burghart, said: “This latest expansion in Manchester not only represents our ongoing commitment to investing in digital excellence, but also signifies our dedication to contributing positively to the city’s vibrant community and economy.
“We are excited to create more modern and productive work environments in the heart of the city, where civil servants from across the North West can be inspired and take pride in delivering the best possible service to the taxpayer.”
