I really dig the utilization of space and great storage with this raised sleeping/lounging platform. Could be utilized in an office or in any small apartment.
for guest room, use stock cabinets for base, make wide enough for small cushion maftress so kids can sleep there.
taj kids bedroom // I wouldn't make this "taj" but I rather like how they are separated and inset. What they mean is Mughal architecture inspired unless they really liked the idea of their kids sleeping in a mausoleum! lol creepy! The linked site doesn't have a description for this but has a lot of other good photos of kid room ideas -pixypi
built in beds make this room more of a hang out with a couch as the main space and not the bed, This would be a great space in a basement area, providing extra sleeping room when family comes to visit or for sleepovers.
