We are considering buying either a climbing frame or a playhouse to DS, 15 months.
Currently we have an area that is just over 3m x 3m (10ft x 10ft) which currently has a plastic sandpit and a small ball pond.
DS doesn't get to use this that often because our garden is SE facing and a bit of a sun-trap. Although the area is bordered on the S, E and W sides by fences and sheds, it still gets very sunny!
We are looking for something to provide some shade, but also to provide something fun to play on that can ideally grow with DS.
A playhouse might generate more shade, but a climbing frame could be more fun.
