A former Inland Revenue office block is to be turned into a business school for the University of Nottingham.
The tax office was home to about 2,000 staff from 1994 after the Inland Revenue expanded outside London.
In 2021, it was put up for sale for £36m after the Inland Revenue (now His Majesty's Revenue and Customs) moved to a new Unity Square block off Sheriff's Way, near Nottingham railway station.
The site was bought by the university, and in 2023 the city council granted planning permission for it to be used as a base for Nottingham University Business School.
However, the university had to get special permission to begin work after the site was given Grade II listed status, following a campaign by the Nottingham Civic Society and Twentieth Century Society.
Planning permission was granted by Nottingham City Council on Friday, the Local Democracy Reporting Service said.
