20x20 Hennin Post & Beam Open Plan Kit

The original Hennin Post & Beam. In 1973, Pat and Patsy designed and built this house with timbers hewn on site using traditional all-wood joinery. Since then we have seen this frame used for dry storage, a starter cottage on vacant land, workshop, bedroom addition, family room addition, two-horse barn, first home, two car garage with game room, or guest house (for the guest who you can tolerate for up to a week at a time). Expand this frame in 10-ft increments.

20X20 PRICING*

Using a special “tusk” tenon, this frame features a 20’ clear span with no interior posts for maximum design flexibility. The kneewall on the second floor is two feet; the 12/12 roof pitch.

Each “bent” adds a 10’x20’ space. Dormers and shed additions are easy to add. The kneewall height is also adjustable based on your needs. The possibilites are endless. Estimate for adding an additional 10 foot bent is decribed below.

Our kits exceed the R-value requirements of the 2012 International Energy Conservation Code (IECC). The details of the structure as well as the insulation can be modified to meet your project, site and budget needs. Remember, most of the timber frames that we build are custom designed!

    After taking their Design & Build course, I had the confidence to build this timber frame house, from a version of their stock plans. And you will too.

    We drove thirteen hours through a blizzard to take the timber framing course and it was worth it. You can tell this family has been teaching people since the 70's. 70's?! These guys are great. I hope to be back to learn but just saying "HI" would be a win. They've probably mapped out every minute of the week for the students but it still feels relaxed. Best of all, I can say with confidence, I can build a house. A timber structure. And I will

    Shelter is a phenomenal resource of skill, intelligence, and good people. I took the two week design/build course and it was wonderful. I left with the confidence to assess my own home and any future home that I may build or purchase. Shelter is the real deal.

    Nothing can beat the hands-on experience that my daughter and I enjoyed for three weeks at the shelter institute. I have kept in touch ever since. I am disappointed that I cannot leave a comment on Pats chainsaw videos. The system does not seem to acknowledge our presence.

    As a second generation carpenter/joiner Shelter Institute's online course is a must for all who are interested in Timber Framing and the enjoyment of life.

    I have found the team to be responsive, caring and helpful. A pleasure to deal with.
