West Norfolk Council will use its Towns Deal funding towards restoring an arts complex and building a new library.
It put forward the two ideas as part of its successful bid for £25m, the maximum Towns Deal grant available.
£4.4m has been slated for developing a multi-user community hub to replace Carnegie Library, with the council contributing an additional £2m.
£5m will be spent refurbishing St George’s Guildhall complex and adding a new creative hub.
The council says it will contribute £750,000 to the project, estimated to cost £9m, and plans to submit an application for Lottery funding later this year.
