Sly, you don’t give the age of your son, but if he is at primary or nursery, these are the places we used or went to, for parties when my children were 11 or under:
St Mary’s Church Hall
St Margaret’s Church Hall
St Simon’s
Putney Library (in the old part, now administered by Putney Art School)
Putney Leisure Centre
All of them have kitchens.
