This is beautiful. From the look of the kitchen island and the bar stools, the kitchen is likely to be nicely done as well. I like the loft for a guest room. I would also consider sliding barn doors as a separation for the bedroom.
floating-bed - could do this for a boy to. Cool and fun idea. Gives more play room on the floor and also doesnt create clutter under the bed. -Screw the kids, I want this in MY room! Make it look like the magic carpet from Aladdin and I want one :) lol
Kids rooms - great way to utilize space in a small room. Ikea bed- Turned upside down the bed quickly converts from a low to a high bed. Love the idea of a lofted bed for a school aged child with a play area underneath
