Circle Square


Circle Square is a flagship development in Manchester City Council’s plan for regeneration in the city and it expects to increase the amount of investment by providing next generation workspaces. The 2.4 million square foot development in the city centre includes two towers, 18 and 14 storeys, with 400,000 feet of BREEAM Excellent Grade A office space. In addition, Circle Square will include retail outlets, services apartments and private residential accommodation, as well as communal space that will be open to the public.

Businesses based at Circle Square will benefit from being part of a growing technology and innovation community in the city. It will provide them with access to world class research and development facilities and the city’s higher education institutions, including the University of Manchester, and Manchester Metropolitan University.

The first two towers at Circle Square are now open and occupied and recently plans to expand to a third site were approved by the council. Construction is now underway on No 3. Circle Square which will be a 14 storey office block, providing an additional 267,000 square feet of space.

Sustainability and the provision of green spaces were carefully considered during the design of No. 3 Circle Square. The development is expected to achieve net zero carbon during construction and BREEAM Excellent status. Once the building is operational it will achieve a NABERS 5 Star rating and an EPC A. The building will also benefit from an all-electric heating and cooling system, with state of the art air source heat pumps, as well as smart metering, roof mounted solar panels and systems to provide fresh air control for occupants. No. 3 Circle Square will also open on to Symphony Gardens which will be a newly landscaped space designed to promote biodiversity.

Billington Structures delivered and erected nearly 4,000 tonnes of structural steel and included within our scope was the design of steel-to-steel connections, the supply of metal decking, primed internal members and intumescent perimeter members.
