  1. Does this plan have an option to lower the pitch. Would like to use for home entrance but think the total height would interfere with second level windows.

  2. I’d like to build a 12×12 timber frame with an 8:12 pitch shed roof. What would be the best plan for me to use for that project?

      The total height is 16′-11 1/16″. And yes, the 12 foot measurements are from outside to outside of the posts.

      You could change the slope. Of course, removing the posts would not work unless the frame was supported by an adjacent roof.

      1. I’m planning on attaching it to my house. Is that possible to have slope changed in drawings I would pay extra if needed

  4. Hi, I have these plans, and I’m getting ready to buy the roofing material. I see that in many designs, when applying the gable end fascia, the fascia juts out from the rafter to create an overhang. In these 12×12 designs the gable end already juts out from the posts by two feet on both sides. Here’s my question. Can the gable end fascia be fastened directly to the rafters, or would you still recommend extending the fascia past the rafters some distance? Is this just a matter of preference? Do you need fascia with these designs?
