UK's most under threat buildings revealed by Twentieth Century Society

Conservation group Twentieth Century Society has announced its 2025 Risk List of UK buildings under threat of demolition or neglect, which includes "millennium-era buildings" for the first time.

Twentieth Century Society launched its latest Risk List campaign to highlight "outstanding 20th and 21st century buildings" in the UK that could soon be lost.

Of the 10 buildings featured, three were completed around the turn of the century, which the group said is the first time buildings from this period have made an appearance in its Risk List.

"For the first time, the Risk List includes three millennium-era buildings," said the Twentieth Century Society.

"Some 25 years after the turn of the new millennium and 30 years since the creation of the National Lottery, which provided the funding for so many of these architecturally ambitious projects, their physical legacy is now increasingly vulnerable and bold new uses are required to ensure their continued survival."

Among these buildings is Sheffield's former National Centre for Popular Music, a faceted steel building which was completed by architecture studio Branson Coates in 1999 and is now at risk of demolition.

Another late 1990s building on the Risk List is Archaeolink Prehistory Park in Aberdeenshire, a building under a grass mound by London architecture studio Cullinan Studio that opened in 1997.

British studio Hodder+Partners' former National Wildflower Centre in Knowsley, which was completed in 2000, is the third building from around the turn of the 21st century listed by the Twentieth Century Society. The studio won the first-ever Stirling Prize for the Centenary Building in Salford, which is set for demolition.

"This year's list demonstrates how the Twentieth Century Society is now decisively moving into the 21st century," said Twentieth Century Society director Catherine Croft.

"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," she continued. "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."

Just one of the 10 buildings on the Risk List is based in London, while the north of England was represented with six buildings, including a 1930s Bauhaus-inspired Sunwin House department store in Bradford, the brutalist 1973 St James' Park Stadium East Stand in Newcastle and the 1935 Grand National Rollercoaster in Blackpool.

"This stark disparity underlines the growing regional inequalities evident in heritage protection, and the challenges of repairing and reusing historic buildings in a climate where they are too often seen as a hindrance to economic growth, rather than a key driver of it," said Twentieth Century Society.

The 1960s Brighton and Hove Reform Synagogue was originally included on the Twentieth Century Society's Risk List, but it has since been saved from demolition by being granted Grade-II listed status.

Other buildings on the list include the prefabricated Patera Prototype in London by high-tech architect Hopkins Architects and engineer Anthony Hunt, the Bury Market Hall in Lancashire by Fairhurst and Son, and the 1938 Penallta Pithead Baths and Canteen in Caerphilly.

At the end of last year, the Twentieth Century Society launched its Coming of Age campaign, which highlighted 10 UK buildings turning 30th that the group believes should be granted listed status.
