Sheffield Hallam University is seeking partners and investors to develop a new Sheffield City Gateway.

Proposals for a 37-storey tower, which will be on the site of the former Nelson Mandela Building on Sheaf Street, have been unveiled at the annual MIPIM real estate conference in Cannes.

The development, which supports but is not a core part of the University's new £220million Campus Masterplan, would feature a mix of uses, including restaurants, a hotel, conferencing facilities and residential units.

A feasibility study and proposal for the new building on Sheaf Street, is currently being developed alongside partners BDP and Lambert Smith Hampton and was presented to 24,000 international property professionals in Cannes last week.

The site was formerly home to Sheffield City Polytechnic's Student's Union, originally the Phoenix Building and renamed the Nelson Mandela Building in 1982, to honour the anti-apartheid campaigner.

Daniel Ladbury, director of estates at Sheffield Hallam, said: “The University plays a vital role as one of the major employers and capital investors in the region and it's exciting to be able to share our ambitious future plans for our estate and the wider Sheffield City Region.

"The proposition has been developed with Sheffield City Council's Core Strategy in mind: the site lies within the Sheffield Urban Area which encourages and promotes major development, vibrant and engaging street scenes."

Last month the University launched its Campus Masterplan - a 20-year proposal to create a sustainable and flexible campus that will allow Sheffield Hallam to achieve its ambition of becoming the world's leading applied university.

The first phase of the masterplan will cost around £220million and will be delivered over the next five years. It includes new buildings for the Business School and social sciences, refurbishing the Students' Union building known as The HUBS, creating a University Green and improving our current estate.
