Art Club/Party Places for my 7 yr old DS

[Primavera]

I am looking for a local art club with a view to having an art party at the venue. More "making" style of art rather than actual drawing. Looking for venues in Bromley, Orpington, Pettswood areas.

There is an art club called Artastic who do fabulous school holiday art-camps. children.club-tastic.co.uk/artastic/ I've no idea if they do parties, but my daughter goes with a friend and they love it.
