I hadn't realised that the kids cubby house and Murphy bed with kid's activity set when bed attached to wall was one in the same room. That is a very creative use of an otherwise mostly unused room.
With the grandkids starting to arrive, and two otherwise virtually unused bedrooms in our place I am thinking that the Murphy bed, at least, is a possible project at our place. I am impressed at the cheap and easy play potential for the little guys. I would never have come up with such ideas, so I am loving this forum as a place to 'steal' inspiration from.
Keep it up.
Bed when folded down. I chose to mount mine Horizontillaly to give a large play surface when the bed is up. It is more common for these beds to be mounted vertically.
