Borgen (Castle) by Vera Vera. This castle comes ready to assemble & doesn't take up too much space. The reading nook is awesome! If we have a kid im totally getting this for them when they start to read
Make the outside of the indoor "playhouse/room" to look like a real house. I would only of dreamt to have something like this as a kid. My kiddo and future kiddos deserve a kickass room they would be proud of.
