18×24 Timber Frame with Purlins

18x24 Timber Frame Plan

This 18×24 timber frame with purlins has great architectural detailing. The struts and knee braces gently curve, creating a beautiful structure. The rafters and purlins of the steeply pitched 12 in 12 roof create their own rhythm – top them with simple metal roofing or add a tongue in groove ceiling to make a wonderful space.

The 18×24 footprint is large enough for many different uses – a combination of outdoor kitchen and dining pavilion, a sweet detached guest house, beautiful carport, or even a generous great room addition to your home. Whatever you use it for, you will be proud to show off your cutting and framing skills when the project is done!

The 25-sheet PDF plan set is ready for you to download as soon as you purchase it. The drawings for this 18×24 pavilion with purlins include renderings, a timber schedule, plan, elevation and sectional drawings, along with piece drawings showing each cut on every timber. There are also 3D drawings so you can visualize the project. The plan set is formatted at 8 /2″ x 11″ so you can easily print it at home or your neighborhood copy shop.

      The total height is 18’8 1/16″ to the top of the ridge in the drawings. It is 18’wide x 24′ long from outside of post to outside of the post 2′ overhangs all the way around it. We don’t have this design in any other roof pitches. We can create one with a different roof pitch though, check out our custom design services page.

    1. There are so many different ways to handle foundations that it is difficult to include a foundation drawing for all the frames on the site in the drawings.  We have completed a bunch of foundation details, you can find them at https://timberframehq.com/construction-details/masonryconcrete-to-timber/.  You should be able to find one that works for you there if not lets set up a time to talk through where you are and what you are looking to build.

      Yes, you can use all mortise and tenons in this frame. The tie beam is in sustain tenon and so we recommend the all-thread connection.
