This lovely 18x12 timber frame pavilion plan  is a perfect size to fit in practically any landscape, yet large enough for so many purposes.  You could  create a dining pavilion, great workshop or sweet backyard retreat. We actually give you two plans when you purchase this 18x12 timber frame pavilion! We  include a full plan set designed as a standalone structure, and a second one planned as a porch to be attached to an exterior wall of your home. You will love showing off your skills with the gently curved braces and embellished rafter ends.

This structure measures 18 feet x 12 feet  from outside to outside of the posts. It is a single bay design that creates a totally clear floor space. There are generous  2 foot overhangs. The top of the top plate stands at  +9’-3” high,and the  top of the rafters are  +17’-7” high. The roof pitch is 8 in 12.  This frame utilizes 2218 board feet  including 8x8, 8x10, 6x8,  and 6x10 timbers

As soon as  you make your purchase, you will receive links to download the pdfs of the plan sets. They are formatted to print best on 11”x17” paper, but you can print a set from home on letter size paper for study purposes.  Both plan sets include 10 pages full of all the information you need for success: 3D drawings, post and rafter plans, section drawings, and detail drawings of the more complex areas of the frame. Both piece drawings sets include 17 pages showing you every cut you will make on each timber. And the pieces are labeled to match the 3D drawings on the plan sets, so you know exactly where each one fits in the frame.

  1. This looks awesome!
    Is it possible (would it be difficult) to double this up for an 18×24? That would be perfect for my workshop.


  2. That would not be a problem, you would just need to mirror the frame. We are happy to make that adjustment in our custom design dept. or that would be easy to do in your shop.

    We do take on custom projects and would like to talk to you further about yours. Check out our page, HERE, describing what we offer and the process of our custom design services. 

    Fill out the design questionnaire so we can understand your needs. That’s the best way to communicate with our team and get an estimate for design services. With that being said, extending a frame parallel with the ridge is one of the lesser expensive alterations.
