12×16 Timber Frame King Post Plan

12x16 Post and Beam Pavilion

Do you want to add interest and shade to your outdoor space or build a tiny home?  Take a look at this nicely sized 12×16 timber frame king post plan! Though small enough for most backyards or small lots, this graceful structure can comfortably accommodate your conversation grouping, outdoor kitchen/dining or hot tub and lounge area.  You can decide to leave the purlins exposed for an arbor effect, or apply shingles or metal roofing over them for more shelter from sun and rain.

What a nice place to relax! The 8 in 12 roof pitch creates a big volume, and the generous two-foot overhangs give extra protection from the rain. You can enjoy this structure open-sided, or enclose it with the material of your choice to create a garden shed or workshop. Or you could decide to add clear panels to create the greenhouse of your dreams!

The PDF plans contain 15 pages full of drawings, 3d renderings, and a timber list, providing you with everything that you will need to cut the frame, fast and accurately. The plans are formatted to letter size paper, easily printed from your home and ready for instant download.

  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?

    1. 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.

      Jose, check out Directory for a list of timber suppliers.

      This is the drawing set for the timber frame pavilion. We do offer the connector kit for this in post and beam here , and for the timber frame version here

  3. 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?

    1. 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.

  4. Eric van Soeren

    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?

  5. 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?

  6. 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

  7. 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.
