(Alexandra Road Park has an outstanding climbing frame)

Suggestions

1) higher border so it's more dedicated to children

2) water fountain

3) under 3 apparatus (swing, slide, side apparatus moveable objects colours and shapes)

4) rugby and football posts in the dog park

5) concrete section with painted numbers and squares to play games such as hopscotch

6) seesaw

7) small hut
