Straw Bale and Timber Frame House Plans

001 a timber-frame-straw-bale-house“Strawtron” is a timber frame house with straw bale insulation, my second major natural building foray after “Gobcobatron”.

We’ve designed the house to use as high a percentage of natural materials as possible, including straw, timber, earthen plaster, and reclaimed flooring. The floor plans were carefully considered to keep the interior space as minimal as possible, while still providing the utmost level of function.

Our ultimate goal has been to make the space and layout as suitable and efficient for this climate as is possible. Northeast Missouri must contend with high heat and humidity, freezing cold and snow, blowing winds and strong rains, extremely heavy clay soil, tornadoes, and drought and floods. This is not an easy place to build!

The Strawtron Building Timeline

Timber Frame House ConstructionApril and I designed Strawtron over the winter of 2011-12, having fully accepted that cob is not suitable for a four season dwelling in northeast Missouri. Gobcobatron would be converted to a three season rental space.

We dreamed up an ambitious plan to create a space that would be ready for living within the year. Our goal was clear from the beginning: we wanted to design an efficient, spacious yet small, beautiful, and largely hand-built home that could serve as a successful natural building model for our particular climate and place.

We came up with floor plans and collaborated with Tom Cundiff, a professional itinerant timber framer (and Timber Framers Guild member) to come up with a timber frame design to suit the structure we had in mind. Tom deftly converted our floor plans into an actual frame, incorporating all of the elements we wished to see in the final house.

These workshops would benefit us by teaming up with experienced teachers to build a house with components with which we had little experience, to spread the labor load and simultaneously get interested individuals involved in building and gaining new skills, to expedite the timeline, and ultimately, to enable a house to be built where it wouldn’t otherwise be possible.

April and I have never worked harder in our lives than in that mercilessly hot summer of 2012, both working on the house and organizing / promoting / hosting two major workshops. We finished the timber frame and the roof in the nick of time, and a huge amount of work was completed during the Straw Bale Workshop. At the end of the summer, we worked alone to seal up the house, and we were able to live in the house for winter upon our return from making income further afield.

In 2013, we finished the living roof, did more interior finish work and plaster, closed in the north porch, built the roundwood spiral staircase, and… prepared to move to Kentucky (yes, we were leaving the home we had just barely begun to enjoy). But that is another story. Strawtron has been a huge labor of love, an even bigger learning experience, and the source of much joy and many memories. It is now for sale.
