Straw Bale and Timber Frame House Plans
“Strawtron” is a passive solar, straw bale-insulated house design with a timber frame, greenhouse for passive heat and extended living space, closed-in north porch, and a 2nd story loft with a west-facing balcony. We have designed the house to use as many natural materials as possible, including straw, timber, earth 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. In northeast Missouri, we have high heat and humidity, freezing cold and snow, blowing winds and strong rains, extremely heavy clay soil, tornadoes, and drought and floods to contend with. This is not an easy place to build!

In 2012, we hosted two natural building workshops to help construct our latest project: this timber frame and straw bale house. Here’s a look at the house design and floor plans. You can also take endless variations here at lamcal.
Here’s a full set of our building plans for the timber frame — including 3D images, floor plans, elevation drawings, etc.: Timber Frame House Floor Plans & Design.
If you find these drawings useful, please contact us and let us know. It’s possible we may make drawings of house beyond the framing elements in the future.
