Yeah, slides would be difficult, but they do sell some with an 8' overhead. You could put some queen size bunk beds in and then a couch that would convert into bunk beds. Cabinets can be purchased from Lowes, Homedepot, etc.... The sky's the limit with designs options. Just no slides.. What ever you do go with, please keep us all updated on your progress should you go with the DIY route.
