This is a custom build, it was sized to fit the available space and designed to meet my main concern of reducing overall height. I appreciate that the sizes may not work for everyone but the concept is an intriguing one and hopefully you'll be able to at least use the design as an inspiration. In this instructable I will discuss the overall process I went through and some lessons I learned along the way. I will use my specific measurements but of course you could always modify as needed. There are a lot of steps but many are repeated as you essentially end up building three beds. I specifically designed the individual bunks to be close to the same so that I could repeat building steps with only slight modifications. That helped me build a bit faster. This also means that, one day, when the bed may begin to feel claustrophobic for the kids, the spacing between beds can be increased or each bunk can even be separated from each other and used as separate beds.
