1 Spinningfields (formerly 1 Hardman Square) is a 90m office tower currently under construction in the Spinningfields district of Manchester city centre, Manchester in the United Kingdom. The development was previously known as 1 Hardman Square which was a 140-metre skyscraper but was cancelled in 2009. The development was revived in 2014 with a 92-metre office tower and the revised design gained planning approval in May 2014. Demolition of the former building on the site, Quay House, began in early 2015 and construction of its replacement began shortly afterwards.
