Any slide for adults in a house is a great idea, but this one contains a water slide. Excellent choice of transportation and you can even get a shower on the way out of bed going down to get breakfast!
"Playroom - LOVE THIS! Even if you only did this in a one-story height basement it would be pretty darn cute. Paint the ceiling, building the little closet "stores" and install mini doors and windows." This is such a cute idea!!.
