A group of residents from Moortown in Leeds is trying to raise money to get green space for community use, before it becomes prime land for housing developers.
Residents' plans include a wild flower meadow, football pitch, allotments, wetlands and 10 eco-homes, to pay for the project.
She said the group of parents and residents were concerned that Moortown Primary, which backs directly on to the field, did not have any grass for children to play on.
Plans include a sports pitch, community building, playground, sensory gardens, allotments, nature reserve area and wetlands, and a small number of eco-houses, to help fund the development.
An open day is being held today at Moortown Primary School.
