Details of the commission are extremely sketchy, but the project will represent the maverick architect's first major scheme in the city.
The job is one of his first masterplanning commissions since a host of northern towns jumped on the Alsop bandwagon following his Barnsley work ( pictured).
The Barnsley designs hit the headlines four years ago when Alsop revealed proposals to regenerate the South Yorkshire town by transforming it into a 'Tuscan hill town'.
Winning the Nottingham project will come as good news for Alsop, who last month announced that his practice had been bought out by the SMC Group.
It is understood that the scheme will start with a major masterplanning exercise, and is then expected to result in building work for the new practice, SMC Alsop.
Alsop was in Nottingham two weeks ago lecturing to council officers about urban design, and it is understood that he then had talks about the project.
