Happy to be corrected by the Trust but I don’t believe the ACV mandates the land has to be for sport, just to benefit the community. So a car park for example
An Asset of Community Value is defined as:
"A building or other land is an asset of community value if its main use has recently been or is presently used to further the social wellbeing or social interests of the local community and could do so in the future. The Localism Act states that ‘social interests’ include cultural, recreational and sporting interests."
So I doubt you could go from a football ground to a Car Park
