Three Gable Timber Frame Garden or Patio Covering Pavilion

Valley and Jack Rafters

Next the valley rafters are cut. They have plumb cuts in either end and ideally a V groove cut in the lower end for fascia boards. Then an angled birds mouth where it sits over the intersection of the beams. And 45 degree angles cut in the upper end where it sits in the corner of the two ridge beams.
Four rafters are installed on the East facing gable end. Like the other gable ends, it’s done first to stiffen the structure before the next steps.

Valley rafters are tricky and I have one chance to get them to fit right. So I took my time. I ended up hauling them up and down quite a few times before they were done and screwed into place.
Connor installed the common rafters across the West end of the pavilion at the same time.

With the valley rafters in place we called it a day.

Connecting the ridge beams to the valley are jack rafters. The ends are plumb cut square to their face where they connect to the ridge beams.

Final Framing of the Three Gable Timber Frame style Pavilion

And that’s the principle framing done. Connor worked on his own to add fascia boards and all the roof strapping. Initially we planned to roll out tar paper over the strapping before adding the metal roof. Connor decided to use plywood instead.

Finishing with Roof and Trim

He painted it flat black first before installing it and I think it looks great. It adds a nice contrast against the stained fir.

I came back to help finish the metal roof and add the trim. Later Connor plans to extend the deck to the North.

  1. Great web site and you tube!!
    I want to build a larger version of your three gable pavilion (22′ x 22′).
    What is your feeling about using GLB? I intend to orient the larger roof plane west for solar panels and “S” cement tile to match the house….. Would I scale up your existing drawing? What would it cost to have a new plan developed? I will need to get approval from the Town of Gilbert (Arizona)..
    Thank you!

  2. Thanks James!
    I think a bigger pavilion with larger posts, beams, and spacings would need to be designed then approved by an engineer and fit with local building codes. I keep most of my structures small so that is not required. I don’t take on any custom work like this. Kent

  3. Maybe I’m not seeing it, but it would be nice if when you buy the plans, it would come with a PDF of this build log so it could be printed as one document for reference. If I did miss this feature please advise. Thanks. Love the plans!

    1. The concrete footings were dug into the ground below grade and below the plywood forms we made. I can’t recall exactly how deep but, we did hit rock so they were not as deep as we would like. Also, a year after that the client poured a concrete pad under the pavilion that surrounded the concrete piers.

  4. I am impressed with the plans and really like the design. I have yet to get to my favorite saw mill and see about getting the order cut. I was hoping to get info for increasing the post footprint and don’t care if it increases the entire pavilion. Just want to build so the posts are 12 or more feet apart. I used you pergola design to help me design a frame for our swing in the back yard and it came out really well. My wife just loves it! I also printed all the other pages that go with the pavilion that were informational and watched the video more than one time and probably will agin before building. Thanks for the plans and great idea building info!

    1. Hi, I have not calculated the snow load. There are online calculators available to do this. Depends on where you live.
