Residents of all ages played football and cricket in a fun day at playing fields in Barkingiside that had been threatened with development.
Save Oakfield Site campaigners organised the event at Oakfield playing fields, in Forest Road, on Sunday.
It became a celebration after proposals for a possible development of 1,000 homes on the land were scrapped.
The fields, used by the Hainault and Clayhall Cricket Club and Old Parkonians, were one of the sites deemed suitable for development by Redbridge Council but the review was scrapped last week because of “public concern”.
Planning boss Cllr Alex Wilson said a new study of the green belt will be “thorough and wide-ranging”.
Events included charity football game between the parents of Buckhurst Hill under 12s and Old Parks FC XI.
Children as young as three learnt the basics of football and cricket in fun sessions run by Old Parks players.
Club chairman Edward Lennard said: “It was a pleasure to host an event that brings the community together in support of a cause we feel so strongly about.”
More than 1,500 people have signed petitions by the Save Oakfield campaign against any development.
