Trilogy Real Estate and Peterson Group’s plans for the transformation of the Grade II* listed Great Northern Warehouse, along with Deansgate Terraces and Great Northern Square, have been given planning consent by Manchester City Council.
The designs propose to revive the Great Northern Warehouse, which is currently used as a car park, by converting the upper three storeys to high quality residential accommodation, stripping away modern additions such as the parking ramps to reveal the building’s historic character and conserve its heritage.
In addition, Deansgate Terraces will be renovated to create a high quality retail street at ground level, with residences on the upper floors. A total of 142 new homes will be created by the development, and 44,000 sq ft of commercial space will be brought to market.
Across the site, public space will be increased by more than 25% to 85,000 sq ft.
Since acquiring the Great Northern in 2013, the partnership of Trilogy and Peterson has been developing a series of proposals in a 10-year plan to bring to life one of Manchester’s most historic and strategically significant regeneration areas.
Robert Wolstenholme of Trilogy Real Estate said: “The Great Northern Warehouse and Square offer one of the most significant regeneration opportunities in Manchester city centre, and we are delighted that this first phase of our ten-year plan to revitalise the site has been approved by Manchester City Council.
“This will be the first part of a scheme to regenerate 6.5 acres of Manchester’s civic centre and to open up Petersfield as a walkable ‘live, work and play’ neighbourhood for the City.
“Petersfield was the location of two defining moments in the UK’s political and cultural history, namely the Peterloo Massacre in August 1819 and the birth of Punk at the Lesser Free Trade Hall in June 1976.
“Maxine Peake’s incredible recital of Shelley’s ‘Masque of Anarchy’ at the Manchester International Festival in 2013, just yards from the location of these historic events, gave us the inspiration to incorporate verses from Shelly’s poem into the architecture of our development – this is our way to celebrate the best of the ‘Great North’.”

Great Northern Square has been reimagined to create a new “urban oasis” that will boost local biodiversity and provide a place for families, local residents and workers to relax.
The existing amphitheatre will be covered over, with a lawn placed on top and broad-leaved trees planted.
The new square will be more attractive and easier to navigate for those passing through. Under the square, a series of water tanks are proposed to collect rainwater that will provide irrigation for the new trees and sustainable water uses within the apartments.
Dean Street, a new pedestrian street, will run parallel to Deansgate, providing retail units ideally suited for independent retailers, cafés restaurants and bars. Public realm on top of the former railway lines will be activated by relocating the entrance to the existing cinema alongside proposed gym and restaurant entrances.
Built by Great Northern Railway between 1896-1899, the Grade II* Listed Great Northern Warehouse is visually striking evidence of Manchester’s industrial past. The original glazed brick lettering along the upper level of all four elevations of the warehouse is a local landmark that can be seen across the city.
Further phases of the transformation are currently in the early stages of consultation, with plans to deliver the project over the next 10 years.
The plans were drawn up by a team of consultants that includes masterplanner aLL Design, architect SimpsonHaugh, Altrincham-based landscape specialist Planit-IE and interior architect Johnson Naylor. Deloitte Real Estate acted as advisors on planning and 2110 Consult was project manager.
