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 gives one foot of headroom for every one foot move into the center of the building.


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.

PLEASE NOTE: Due to material const increases, our kit pricing will be increasing on January 1, 2015

Green timbers are planed, chamfered, and oiled to protect the surface, reduce checking, and slow the drying process. All timbers are planed full dimension unless otherwise specified.
