outdoor toy recomendations for communal garden

[pud1]

i live in a ground floor flat with a communal garden space. to get to the garden i have to go out my front door, down the hall way, out the front door and round the back to the garden. i am looking for some outdoor toys for my 2 year old dd that are:

1. transportable ( although could leave them out at a push)
2. not too expensive

am thinking along the lones of pop up houses. would be greatful for any suggestions

I would definitely get the pop up houses/tents and tunnels. My DC played with them for many years, they were worth every penny.

big beach ball?
small trowel, if she's interested in digging about?
is there a tap? sounds odd but we had a great time running around through sprinkler hose when we were growing up (in hot weather, obviously...) though hose would prob have to be kept outside.
