This is partly due to the natural trombe effect present in the straw bales, which allows them to store and release heat or coolness as needed. The cost of building a straw bale house varies significantly, but figures between $130 and more than $450 are common. The cost depends on your location and the availability of materials and labor. For example, you could build a straw bale house in Southern Oregon for around $225 per square foot. A growing interest in sustainable building solutions has led to the development of several straw-bale houses. One such example is the SCL Straw-Bale House designed by architect Jimmi Pianezzola.

Finally, engaging with the straw bale construction community can provide access to experienced contractors and resources on best practices 4. One common issue with straw bale houses is the potential for moisture damage, as moisture can lead to mold growth and cause the bales to degrade. It is essential to properly design and build the house to avoid this, including the use of a moisture barrier and adequate ventilation.
Straw bales are biodegradable
These are cassettes manufactured off-site and used in the straw bales to enhance their insulation capacity. With the load-bearing approach, you’ll not see beams or posts used to support the roof, as is the case with conventional construction techniques. Built between 1896 and 1897, the Schoolhouse in Nebraska became the first documented evidence of straw bale construction in the United States. To prevent moisture damage, proper design considerations must be made, such as incorporating a moisture barrier, good roof overhangs, and using the appropriate materials. Moreover, proper ventilation strategies, such as the use of vapor-permeable materials and passive ventilation techniques, can help maintain a healthy indoor environment and prevent moisture accumulation.

Building codes and regulations play a significant role in the construction of straw bale homes. Since 1990, straw bale construction has been recognized by some regional building codes, and in 2015, it was included in the International Residential Code. This inclusion has allowed for wider acceptance and understanding of straw bale construction techniques, making it easier to comply with building regulations. Please note that local building codes may vary, so it is important to consult with local authorities when planning a straw bale home. It is also important to work with experienced builders or architects who are familiar with straw bale construction techniques. By using materials like straw bales, earthen plaster, and reclaimed wood, you are not only benefiting the environment but also preserving the aesthetic appeal of natural elements in your home.

Everything You Need to Know About Straw Bale DESIGN
By all means, build it yourself, just make sure you know what you are getting yourself into. Discover how an ecological way of building is creating homes and structures of high quality that meet state and local building codes and regulations. Unfortunately, materials lists are not included with our plans as part of the standard set.

As such, when straw bales used in construction begin to break down, they can be easily recycled back into the environment. This process helps reduce waste in landfills and preserves valuable resources. With the world’s population growing and resources diminishing, more people are looking for sustainable building methods. Inclusion of a basement is “always possible,” Morrison says, but it requires interior footings and stem walls to keep the bales above grade.
The core material of a straw bale house can be returned to the earth at the end of its life. The straw, the natural clay plaster, and most other parts can simply be plowed back into the soil to decompose naturally. Overall, straw is a sustainable material that has plenty of redeemable features when it comes to construction, though it may not be suited for everyone or every situation. Take time to look at the risks and rewards (and limitations) while considering a straw bale house.
The Building Process
Furthermore, straw bales don’t combust easily because they are coated with a vapor-porous plaster. The final step is to apply internal and external plaster to protect your straw bale wall and keep the house warm in winter and cool during summer. In both cases, maintain the recommended straw bale wall thickness of between 18 and 24 inches (45.72 and 60.96 cm) to ensure you get the full benefit of the insulation the bales offer. On the other hand, if you go with the post-and-beam infill method, start by erecting the frame and then fill the empty spaces between the beams with straw bales.
Since the straw bales are tightly packed, there isn’t much airflow available to sustain a fire. Get ready to fall in love with this spacious two-story home, originally designed for a location where the allure of shade takes center stage. This set of straw bale house plans includes the comfort and functionality of a generous kitchen that opens up to the family living area. In addition to being low in toxins, straw bale houses are also resistant to mold and mildew growth. This is crucial in maintaining a healthy living space, as mold and mildew can cause various health issues.

The uncommonness of straw construction however is perhaps its main downfall, as the lack of understanding of the material in the general public makes obtaining insurance coverage often a difficult task. So in an attempt to spread the word, we have rounded up some of our favorite straw houses and structures that may not huff and puff, but will definitely blow you away. Eddy fruchard – construction specialist – explains that this process has been very popular for the last 15 years, and according to him, this type of home represents the future of construction.
The thickness of a straw bale wall means you are sacrificing some interior space. They are typically 18 inches thick, which is substantially thicker than a stick built wall covered in sheetrock, which is usually closer to six inches thick. As a result, if a straw bale home and stick built house have the same footprint, the straw bale structure actually has less functional interior square footage. Insects and rodents may try to take up residence in the bales, especially when they are exposed during the building phase or are not properly finished and maintained over time. Similar to the point above, getting building permits for a straw bale house might be challenging as well. City officials may be uncomfortable with the concept, especially if you are not in an area where it is a widely accepted building method.
A moisture barrier is then applied to the surface of the walls, usually made up of earthen plasters, stucco cement, or gypsum plasters. You might be surprised to see how much a project cost varies based on its location. If you want to get a sense of things in your area, talk to the local builders. If you want to translate a price from another area to your own, consider purchasing a book on estimating tables that offers location variables. Straw bale houses are making a comeback, and one notable reason is their impressive fire resistance.
Thus, straw bale houses are efficient and sustainable, with a wide range of environmental benefits. A traditional straw bale building uses layers of tightly packed hay or grain stalks made from loose straw by a mechanical baler to form thick walls. The walls are then covered with plaster or stucco and left to dry, creating an airtight seal that keeps the house warm in winter and cool in summer. A straw bale building utilizes harvested stalks of wheat as its primary building material.
