The Minim House looks to have a roof pitch of 3/12. I plan to go with a bit steeper pitch of 9/12 for more headroom, but still safer to work on than what seems to be the standard 12/12 roof pitch for tiny houses. The Minim House does not have lofts due to the shallow roof pitch. I am thinking of building 10' high walls in my tiny house. With a loft at 7' high, this would give me about 6' of height at the peak of the loft. The picture below shows the Minim House roof pitch and the rainwater collection system. I also have rainwater collection on my list of requirements.
