Holy cow that's a lot of kids in one room! Cool idea though. This is a pretty awesome idea for a room where the kids will play and sleep. Freed up floor space during the day and space for the beds at night.
Triple bunk bed plans - build your own. Great to have a spare bed for sleepovers!just an idea, build the third bed at desk height, create a desk top that can be removed to convert it to a bed when needed.
I think this under-bed clothes-by-day organizer would work even better for the girl than the hanging sweater bin does, because I could drop clippies, socks, even shoes into each compartment and not worry about them falling out when she grabs her clothes.
