Broadland director Richard Guthrie said: “The Westway Boxing Club is a shining light. This is a really good news project.”
The council’s funding is expected to be approved when its decision-making executive board meets on 16 June.
A report said the redevelopment work would include extra gym space, a main training hall with full size boxing ring, toilets, changing areas, a cafe, classrooms and storage space.
“The project will double the club’s capacity, expand provision for young people and vulnerable adults, and create space for alternative education and specialist programmes including a project for people with Parkinson’s disease,” the council’s head of localities, Marie-Ann Jackson, wrote.
Rhodes said: “This isn’t about one person, it’s a community project. I’m leaving it with the younger coaches, Ryan Ashworth and James Cliffe, and our great committee members. They will take the place into the future now.”
