If it were me having small children playing, I would, without a doubt put up 5/6ft fencing.
Trellis with clematis is not green all year round, at the moment my montana looks awful, like a load of dead straw, you need something enclosed. Even the quickest growing trees/shrubs wont grow big enough by the summer when the little ones are out playing. Maybe your neighbour wants to look in!
My daughter is a childminder and has 6ft high fences, even along the roadside where they should be only one metre, but in the circumstances was allowed to leave it.
