A new gym, a school expansion, a library extension and new changing rooms at a popular park have been earmarked for a share of millions of pounds.
And a community sports hub has also been handed a boost in its bid to secure millions to expand further.
Council leaders met to decide how to spend money raised through the community infrastructure levy - a tax on developers who have built homes in Norfolk.
In setting out its five-year plan for how to spend that cash, members of the Greater Norwich Growth Board - made up of leaders from Norfolk, Norwich, South Norfolk and Broadland councils - added projects in Norwich, Wymondham, Aylsham and Horsford to the list.
The biggest share will go to Wymondham High Academy, which councillors agreed should get £2.5m for its proposed expansion.
Planned for 2025/26, that will be the fourth phase of development to meet the growing pupil demand from the housing development in the town.
The expansion is expected to include a new gymnasium and a new design and
technology block.
The board agreed to make £650,000 available to The Nest in Horsford, on the edge of Norwich, to help with its efforts to secure £8.1m for its expansion.
The sports community centre wants to build a new multi-sport indoor hub, including a sports hall, climbing wall, classrooms, a fitness studio, cafe and changing rooms.
A pledge of match-funding will help The Nest with its applications to secure money from other sources, including from the government.
The board also agreed to award £400,000 to Aylsham Gym and Fitness Hub - a proposed community centre at the town's high school site.
Just over £330,000 was earmarked for Eaton Park in Norwich, to renovate the changing rooms in the central pavilion.
And almost £200,000 was set aside for an extension to Plumstead Road Library, in the east of Norwich.
John Fuller, leader of South Norfolk Council, said he was "enthused" by the schemes and said they were precisely what the community infrastructure levy money should be being spent on.
