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.

39 thoughts on “12×16 Timber Frame King Post Plan”

  1. How hard would it be to add a floor to this design. I’m looking at making an outdoor living space but I want to have it off the ground so I don’t have to poor a concrete slab and spring drainage isn’t as much of an issue.

  2. Good Morning. Two questions:

    1. I believe the City where I live will require an engineers certification. Have yo ever obtained one in any location for this plan?

    2. I want to add a shingle roof. Looking at the plan, seems I can do this by adding fascia boards to the edges of the rafters down the 16′ sides and adding roof sheathing on top. Seem doable?

  3. Yes, this set of plans has been reviewed by an engineer, every location is slightly different though. Where are you planning on building it? We can work with you and the engineer to get you a sealed set of drawings for you and your location.
    I would recommend that you put 1 1/2″ tongue and groove or 3/4″ tongue and groove then 3/4″ sheathing on the ceiling and then you will have 1 1/2″ of material to nail your shingles to.

  4. Are the Measurements of 12 x 16’ taken at the total outside of the rafters or is that post to post
    I need plans for a 12×16 plus the overhang
    Thx
    Jim

  5. I’ve raised the two bents and will fell trees for the 20 foot beams soon. Thinking ahead to the rafters, are they fastened with nails and screws, or is it possible to stick with pegs?

  6. All three will work, I strongly recommend using a good structural screw with min. 4″ embedment into the opposing timber, ASSY, GRK or Rothoblass TBS (we carry in the shop), a peg or a nail would be a draw for 2. This frame can stand for the next 100+ years and may be taken down and put back up during its life span. Screws make all that a lot easier.

  7. Can this structure be built using 6×6 posts and 6×8 beams, both of Douglas fir, or do they have to be 8×8 and 8×10 or 8×12?

  8. This plan is “perfect” for except I only have space for a 10X16. Can you modify the plans for that? Also, are these timbers full dimension or nominal size?

  9. I would like to build a small blacksmith shop. Can the plans be shortened pit on a stone knee wall with a bottom timber to fasten to top of wall

  10. I’d love to see a design based on this or the 10×14 king post plan which adds a 3rd gable in a T shape as long as it is wide. This would make a great backyard pavilion to cover a large table as well as an outdoor kitchen area.

  11. Katrina Williams

    Most of our plans are rated for 40 psf but that depends on other factors like seismic areas, wind load, wind exposure, timber species and more.  When in doubt we recommend that you consult an engineer. We do offer engineering services as an add-on to our standard plans.

  12. Which plan do you think would be easier to modify? I’m limited to 12×9. I like the simplifications in the 10×10 king post using the Rothoblass Alumini connectors, but this one (12×16) would just need the front 12’x8′ section and make it 9′.

    Also the 10×10 says it is using 6″ material is this one 8″?

  13. This plan uses 8x material. It would definitely be easier to shorten this in the ridge direction than to modify both dimensions of the 10×10.

  14. I am planning on building a gazebo then fitting it out as an outdoor kitchen. I would like to know if this design can be modified to allow for 8 metres in length and 4 metres in width? This would be the overall length of the roof and as the roof does overhang the posts on the length the post centres would be approx 7 metres. I can modify the plans of course as my required dimensions differ from your design my major concern is that I may have to fit another post due to the length. Are there other options like upsizing the beams/posts to allow for the load as I would prefer not to have to add additional posts.

  15. Steve St. Pierre

    Is this plan available in a 12′ wide x 20′ deep? I am planning on building a carport and like this design. The 12′ width is perfect. Also, any alternative for the roof pitch on this design (lower pitch).

    Thanks!

  16. We would be interested in your 12’x16′ Cabana Kit and trying to put a budget plan which would have to include all the hardware like screws and bolts etc. Is there a list on web site to maybe get an idea of how many bolts etc, to include in our budget?

  17. 2 questions. Can this plan be lengthened to be a 12×24 with a post in the center, or can the 16×24 be cut back to a 12×24? Roof pitch 8:12

    Do the plans come with drawings/measurements for the mortises and tenons, and the timber splice?

    Looking to make this design into a greenhouse with added lumber and sitting on top of a 32″ stem wall, ICF. All lumber milled by me and will be white oak.

  18. It would be much easier to extend this plan to 24′ than to change the width of the 16′ plan. Our plans come with fully dimensioned piece drawings showing all the cuts.
