If you are looking to create a new facility for a specific sport, the best source of advice will be the national governing body for that sport.
If you are looking to create a new facility such as a pavilion then Sport England have plenty of advice on their website. There is also advice here on drainage projects and other improvements to playing fields. Another source of information is the Institute of Groundsmanship.
The other Home Country Sports Councils will also provide advice to landowners and groups wishing to improve their facilities.
We also have some information on possible funding sources.
