DIY Loft Bed - A loft bed is a great space saver for a kid's room! A younger kid could use the space underneath as a play area and an older kid could use it as a study area.
Love the idea of creating a separate space by raising the floor in part of an open loft; then you can hide a bed when not in use
Great way to use wall space in a tiny house. Also, this page has a picture of GORGEOUS doors.
