![]() ![]() If I were to do a short 2nd story wall, I'd use continuous wall studs rather than have that hinge point of the separate wall. I've read many threads and have considered a ridge beam, various trusses, etc. It does impose a couple of other design constraints (need to provide support down to the foundation) but I would see it as an option to get your headroom. Why not consider a ridge beam and rafters? You don't mention cabin size but an appropriately sized LVL beam, although adding some cost, might simplify the build (rather than trying something more complex) so might even be cheaper in the end if you factor in time and effort. I see a lot of cabins up here done the way you describe, but have never heard of a squished sleeper (although with Alaska snow loads, the roof pitches are steeper). I wont have time to sketch is up, headed out of town.Ĭhrisser, so how is the construction you want to avoid different than most two story houses, other than the second story has really short walls? The weight of the roof is transferring to the walls one way or another, and the collar ties (and the connection to the top plate) if correctly done are stopping the rafter spread. Now take a large tie like a 2X6 or more and run it up like a scissor on one side, then do the same on the opposite side, then fill in the cross point with a board the full length and you have the scissor rafter. OK, you have your rafters in the V or pitch you want. How about scissor rafters, not scissor trusses. There are other options, have you decided on a size and are there height restrictions ? Stick framed I would probably build the walls full height ~10' and run a let in ledger at 8' to rest the cj's on. Trusses also often use a cantilevered overhang to gain more useable space. On these I'll plate both sides of the joint with scrap plywood and plenty of nails to reinforce the tired connection there. In older work there was often a flatways board nailed on the top of the cj's called a raising plate that the rafters were nailed to. The rafters have just a level cut and rest on the ceiling joists. The one I'm working on now is 14' wide with 16' ceiling joists that cantilever over the walls, forming the overhang. Then insulate the soffit and then the main floor side wall. It may be best to treat the small triangular area as conditioned space and exten insulation in/on the roof down to the ceiling joist. Think ahead to how to insulate the roof and short loft side wall before starting to build. That joint would be bearing half the roof weight in a normal rafter roof, as well as the horizontal forces. Well, that and any building inspector if there is one. How to make the rafter meet the ceiling joist and have the required strength is the main issue. My idea, I haven't built it but one similar. Is this a sound configuration? Does this method have a name already? ![]() This gives rafter ties much lower than would be had by just having them in the lower 1/3 of the rafter and it makes it very easy to box the rafters in with a soffit - essentially the second floor joists do triple duty - floor joist, rafter tie, and soffit structure. The short wall carries all the vertical load.īut then, if planned right, those joist extensions could intersect the rafters outside the building (easier with a steeper pitched roof). What if the joists on the lower box were extended so they stuck out past the walls? Then the short wall is erected on top, and the rafters are set on the short wall. Have an idea that I haven't seen posted and was wondering what you guys thought. Mitigated by a metal roof, and probably limited snow load, but still probably not something I want to sleep under during a windy snow storm.īeen thinking of ways I'd do it differently and read a lot of posts. I think it was a 4/12 pitchįrom reading this forum, I looked at that and thought it was a bad idea. ![]() He built an 8' high box, then added a 2' high wall and set the rafters on it. Like a lot of people here, planning a cabin with a loft and want to maximize ceiling height up there.Ī neighbor built a cabin about the same size and had me over to look at how he did it and give me some ideas.
