Tiny House Stand-up Lofts Are a Crazy Space Saving Innovation
I am a residential designer specializing in tiny homes and small spaces. I recently had the opportunity to design a stand-up loft, and it blew all the other lofted bedroom configurations out of the water.
Conventional Lofts Only Have 36"-42" of Headroom
Once you add in the thickness of the mattress of 8–12", there is not much headroom left over. Some clients choose to have a skylight over their bed, which adds a few extra inches of headroom. Keep in mind that the skylight frame contributes to the final height of the tiny house. So if you have a flat roof, your skylight will count against the allowed height.
Another way to get more height in the loft is to simply lower the ceiling on the ground floor. 80" (6'-8") is the lowest that is permissible. So you could theoretically have up to 48" of headroom in a tiny house loft. You could also do steel joists and simply run floor boards across. This would have less privacy, but it would give you more headroom.
