My House of Giggles: One giant family bed (if you can't beat 'em, join 'em). Funny, just the other day my 4 year old suggested doing exactly this!
Schicke und unübliche Bettrahmen-Ideen (auch zum selber bauen) | Dekomilch
DIY king size bed made from a few 2x4s cut to fit the space between shelves, 3 ikea expedition shelves, metal brackets to hold it all together.... Voila! Even has a nice little bench at the end for sitting on while putting on shoes etc.... We love it!
