Hi I am building a small treehouse bunkie (12x12) and am trying to decide on roof design. I want to build it with a half loft as well so decided on a gable 12:12 roof for extra head space when up there. My main dilemma is to have the loft looking out of a large window. How can I support a ridge beam without a post at one end (due to large window)? If that is not possible, would a ridge board roof have adequate bearing wall horizontal support with ceiling rafters for just half the roof, i.e. vaulted ceiling for half the bunkie? I've attached drawings if this doesn't make any sense...
