12×16 Timber Frame Shed Plans

12x16 Timber Frame Shed

This 12×16 three bent timber frame shed has two doors and the roof pitch is 12/12. One door is a large door on the gable end. It is 6′ wide. The second door is on the side eave wall for people to access the inside of the shed.

The additional pictures shown are of the shed made by a customer of mine. He finished off this shed with vertical board siding, asphalt roof shingles, windows on the eave wall and the back gable end, a window over the large gable end external sliding door as well as added some sky lights between the rafters for natural light for the loft area.   This plan set does not include the lean-to addition on the side of the shed.

Or you can use 2″ plans for the first floor deck and roof, either way these plans can be used for both sizes of decking. The plan set is printed on 8 1/2″ x 11″ standard letter size paper, non bound. You can copy a page to take out to your workshop and use to make notes, keeping the original for future reference.

This frame completely customizable to your own needs. You can make the door narrower if you choose by moving the mortises in the tie beam and sill, make the large gable end doors hinged and not an external slider, add more doors if you want,make the frame taller by making the post longer and you can enclose it with vertical siding or horizontal siding if you add blocking.

  1. Do these plans include detailed view of each piece, including size and location of joints? Multiple views of each piece (front, back, sides, top, bottom)?

    1. Pat, we don’t have any greenhouse plans specifically, but many of the plans would easily convert to greenhouses just by your choice of cladding and roofing material…

  2. What kind of foundation (pier, block, skid?) would work best for timber frame sheds? Would you need something stronger than block?

    1. There are a bunch of different ways to handle the foundation. Blocks work well and it what I used on my workshop, you do have to fill the cells of the blocks if you are planning a post to bear on it.

  3. Couple quick questions. Do you have anything this size but more of a tiny house, rather than a shed? Does it have a loft? And finally, any recommendations on insulating?

      Jared, here are all of our 12×16 plans. This one might be suitable for a small loft, depending on what you are using the loft for and the headroom you need. As far as insulation, we recommend Spray Foam Insulation if you are not using SIPs

    Can you tell me if there is any plan available with adding an enclosed lean to/porch to this plan. Something similar to your 16×20 cabin porch but enclosed.

  5. Brady and Katrina:
    I don’t have that frame drawn with a porch/lean-to right now. I’d have to make it a custom plan. I am so busy at the mill right now that I can’t get to it for a while.
    Sorry about that.

  6. How tall is the ceiling/door clearance on the first floor?
    What size roughly are the pillars?
    This is what I’m looking for to build next fall. Just need to make sure timber on my property will be wide enough.
