Outdoor play equipment for nearly two-year-old

[Chocolatestain]

DS is 21 months and pretty advanced in his walking, climbing and balancing (not so much in all the other stuff!). He is very active and loves outdoor play. We are about to move from a house with a tiny garden to one with loads of space and I'd like to get him some outdoor stuff. Does anyone have any recommendations? I was thinking of something he can climb on that maybe has a slide, as he loves slides. I obviously want something that us safe and appropriate for him but that he won't grow out of too soon. Also, any thoughts on ride-on toys and Wendy houses? Thanks.
