16×20 Heavy Timber Pavilion

16x20 Heavy Timber Pavilion Birds Eye View

Are you looking for a plan for a roomy workshop, carport, or cabin? This 16×20 heavy timber pavilion plan is just the right size for those uses and many more. You could install siding of your choice to make a cozy, weathertight structure or leave it open for an outdoor living space. You might want to adorn the frame with a tongue and groove ceiling above the rafters.

The king post trusses add a classic style to this beefy frame supported by 8×8 posts. We offer two roof pitch variations for you to choose from: a 6:12 pitch and an 8:12 pitch, which gives you a ridge height of almost 15 feet! Also, if you want the look of a timber frame without cutting joinery, we include plans to convert this 16×20 heavy timber pavilion into a post and beam with metal connectors.

When you purchase this plan, you can instantly download the 23-page PDF set of drawings. We include fully dimensioned plans, sections, and elevation drawings along with 3D renderings to help you visualize the final product. We provide detailed drawings of each cut on every timber, so no guesswork is involved in cutting this frame. And we also provide you with a timber list, so you can easily budget and shop for your materials.

  1. Is there a difference between the King post and Timber frame other than the 4′? They look the same…

  2. Katrina Williams

    Yes, you could place this on a wooden flooring system. The height to the top of the rafters for the 6:12 is 14′-4 3/4″

  3. What additional engineering would you need for the Houston area since we experience hurricanes every summer?

  4. William Stubblefield

    I assume that the 16×20 pavilion uses 8×8 posts? If I built this structure, I would fill in the sides with additional timbers on either side of the doors and windows. If you added additional timbers could be posts be scaled down to 6×6? I am thinking about handling such large timbers

  5. Katrina Williams

    The posts are indeed 8×8. We could never recommend your downsizing the timbers without consulting an engineer.

  6. Is the frame tall enough to do lean to sheds off the sides of the frame with conventional framing?

  7. It is 8′-7″ to the top of the bent girt which is about the same as the bottom of the rafters.
