After we've collaboratively chosen the ideal wood type for your project, we proceed to source the highest quality timber through our network of trusted mills. Ensuring that every piece meets our exacting standards, we then transport the timber to one of our cutting facilities. There, the joinery is meticulously crafted using CNC machines. Every joint, drilling, mortise, and tenon is cut with precision, adhering to tight tolerances for impeccable quality and fit.

Following the cutting process, all timbers are systematically labeled according to the production numbers assigned during the creation of your model and plans. This meticulous process ensures that every component of your timber frame is prepared with the utmost attention to detail, ready for the next phase of your project.

Included with your package are all the pegs, fasteners, screws, and connectors you need to put your ready-to-raise frame together. You will also get a detailed list for you to refer to while raising your frame.

  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.
    Thanks

  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?

  3. What is the total height? Also just to confirm 12 x 12 is measurement to outside corner of posts?

  4. Katrina Williams

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

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

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

  8. 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?

  9. Is there a list of the timber dimensions. This is exactly what I’m planning on building. I’m planning on building with black oak 8×8 beams.
