The former National Centre for Popular Music closed in 2000 – just 17 months after it opened in March 1999. It was designed by Branson Coates, and featured four massive steel drums around a central atrium space. It is one of several Millennium-era projects on this year’s list. Sheffield Hallam University, which acquired the site for use as a student union in 2003, has recently announced plans to move its student union closer to the city centre, leaving the Hubs building, as it is now known, with an uncertain future. The university has not ruled out its demolition. A spokesperson told the AJ that it was ‘looking at several different options for the building in the longer-term’ as part of the next phase of a campus development plan.Advertisement The Twentieth Century Society’s Risk List 2025 (see full list below) features a further five buildings across the north of England. The society says this is indicative of ‘growing regional inequalities evident in heritage protection’. The buildings include a 1930s rollercoaster in Blackpool and a 1930s department store in Bradford as well as Bury’s early-1970s market hall and a FaulknerBrowns-designed stand at Newcastle Football Club’s St James’ Park stadium.  The final northern scheme is Hodder + Partner’s National Wildflower Centre in Merseyside, which has been closed since 2017 when the charity behind it entered liquidation. In 2023 Knowsley Council suggested it would remove the building amid problems with arson and graffiti.  The Risk List features a third millennium-era project: Cullinan Studio’s Archaeolink Prehistory Park, which opened as an archaeological tourist site in Aberdeenshire in 1997. The park closed in 2011 due to low visitor numbers and was sold to developers in 2024.  Part of the site is earmarked for housebuilding, but the subterranean visitor centre is now back on the market for £150,000. The Twentieth Century Society has expressed concern over its dereliction despite hopes that a café or shop could yet occupy the space. Advertisement Also on the list are the Penallta Pithead Baths and Canteen, a 1930s International Modern bathhouse for coalminers, which faces dereliction despite Grade II*-listing; and Michael Hopkins and Anthony Hunt’s Patera Prototype in soon-to-be-developed Royal Docks, an ‘early relic of the High-Tech movement’.  A 10th and final project on the Risk List appears to have been saved since the list was drawn up. The 1960s Brighton and Hove Reform Synagogue has been listed at Grade II, which is likely to end plans to demolish flats on the site.  The building is only the second post-war synagogue to join the National Heritage List for England and features ‘extraordinary, technicolour’ stained coloured windows dedicated to the memory of the Holocaust.  The windows, by artist John Petts, have been dubbed ‘the Guernica of Brighton’ and described by National Portrait Gallery chief curator Alison Smith as ‘one of the greatest religious artworks of the 20th century’.  Twentieth Century Society director Catherine Croft said of the Risk List: ‘The three Millennial projects highlighted may feel very young to be recognised as heritage, but they’re now a quarter of a century old and the product of an era where unprecedented public funding delivered some ambitious and extraordinary projects.  ‘They are simply too good to lose. Some of the businesses and organisations behind them may have failed, but we’re left with an architectural legacy capable of inspiring and energising new uses, that make our towns, cities and landscapes richer and more interesting places to live. ‘The threat to these buildings is tempered with the wonderful news that the Brighton and Hove Reform Synagogue has been Grade II listed as this campaign went to press. With the 80th anniversary of the liberation of Auschwitz being commemorated in 2025, the destruction of this luminescent memorial would have been unthinkable.’ The Twentieth Century Society’s Risk List 2025 Patera Prototype, Newham, London – Michael Hopkins and Anthony Hunt, 1982 Sunwin House, Bradford, West Yorkshire – WA Johnson, 1935-36 Bury Market Hall, Lancashire – Fairhurst & Son, 1969-71 St James' Park Stadium East Stand, Newcastle – FaulknerBrowns, 1973 Grand National Rollercoaster, Blackpool - Charles Paige, Harry Traver and Joseph Emberton, 1935 Former National Wildflower Centre, Merseyside – Hodder + Partners, 2000 Former National Centre for Popular Music, Sheffield –  Branson Coates, 1999 Archaeolink Prehistory Park, Aberdeenshire – Cullinan Studio, 1994-97 Penallta Pithead Baths and Canteen, Caerphilly – Miners’ Welfare Committee Architects, 1938 Brighton and Hove Reform Synagogue, East Sussex - Derek Sharp Associates and John Petts, 1967-68 More information on each of the Twentieth Century’s Society's top 10 at risk buildings can be viewed on its website
