I absolutely love this set up and storage Family bonus room with slanted ceiling. Custom built ins and daybed create a great place to hang out with the kids and comfortable space for an overnight guest.
Awesome idea if a bedroom is against a hall closet! Never really use the entire hall closet anyway! Save on the clutter and fill uneeded space in the closet to be used for more floor space in the bedroom!
Good idea for a small space or loft area in an old home, but rather than a second bed next to it, make an actual CLOSET. Love old houses, hate the lack of closet space. *I would add doors to both closet and bed alcove just because.
