In a fascinating conversation on the Less House More Moola Podcast, host Laura sat down with Sigi Koko, an architectural designer dedicated to natural building. Koko, who exclusively designs homes using locally available, abundant, and sustainably harvested materials, illuminated a path towards creating healthy, energy-efficient, and community-rich living spaces. This discussion unveils the evolving landscape of natural building, from increased public awareness to the profound benefits for both homeowners and the planet.

The Journey into Sustainable Architecture: Sigi Koko's Natural Building Story

Sigi Koko's journey into natural building began during architecture school, sparked by a professor's course on indigenous architecture. Inspired by the simple yet beautiful buildings that harmonized with their environment and available resources, Sigi questioned why modern construction had abandoned these time-tested principles. She advocates for a return to buildings that "read" their climate – homes that naturally respond to hot or cold conditions, water scarcity, or abundance, reducing reliance on energy-intensive systems. This philosophy resonates deeply with the concept of "regenerative business," working with nature rather than against it, a stark contrast to the often nature-defying practices of conventional construction.

Shifting Tides: Growing Awareness of Eco-Friendly Construction Materials

A significant shift Koko has observed over her decades in natural building is the dramatic increase in baseline knowledge among the public and professionals. When she started in 1998, she frequently had to begin conversations by explaining the very nature of materials like straw bale or clay. Today, there's a broader understanding of materials like hempcrete, living roofs, and various plasters (clay and lime). This shift means conversations can move beyond fundamental explanations to addressing specific curiosities and reservations, empowering individuals to say "yes" to natural building. This evolution, from basic education to detailed implementation discussions, offers Koko hope that mass acceptance is within reach, pushing us closer to a "tipping point" where natural building becomes common knowledge and practice once more.

Overcoming Obstacles: The Persistence Required for Natural Home Construction

Despite the growing awareness, pursuing a natural building route still demands persistence and patience. Sigi highlights the "gaps in implementers"—the shortage of skilled and knowledgeable builders in natural construction. Homeowners often face resistance from conventional builders who prefer to stay within their comfort zones. However, Sigi acts as an advocate for her clients, navigating the complexities of permits and builder reluctance. The ideal scenario involves increasing the number of natural building implementers, fostering education among insurance companies and permit officials, and engaging real estate agents, all of which would streamline the process and reduce the "grittiness" currently required.

Debunking Myths: The True Cost of Natural Building vs. Conventional Construction

A common question revolves around the cost of natural building. Koko clarifies that if you build the exact same structure using natural materials versus conventional ones, the overall cost would be similar. The key difference lies in the distribution of expenses: natural building involves higher labor costs but lower material costs. This often means directly supporting skilled individuals rather than large corporations. Crucially, many aspects of natural building, such as plastering or working with straw bale, have a short learning curve. This accessibility allows for "work parties" and homeowner participation, significantly reducing labor costs and creating opportunities for substantial savings.

Practical Steps to Incorporate Green Building Techniques into Existing Homes

For those looking to dip their toes into natural building, Sigi suggests starting with a "pot holder project"—a small, low-stakes endeavor where learning and potential mistakes won't cause distress. This could be a chicken coop or plastering a garage wall. The simplest and most impactful entry point for existing structures is the use of natural paints and plasters. Clay plasters, in particular, offer remarkable benefits: they regulate humidity, moderate temperature, and absorb airborne toxins. Sigi shares a compelling example of how clay plaster in a bathroom can prevent condensation and mold, a common issue with conventional latex-painted drywall.

Beyond finishes, more radical renovations can involve natural insulations like hempcrete or straw bales, or even the creation of living roofs. These solutions offer improved energy efficiency, a healthier indoor environment, and a stronger connection to the natural world. The choice of project depends on the homeowner's desired involvement and the extent of renovation.

Beyond the Walls: The Community and Financial Benefits of Eco-Friendly Homes

Engaging in natural building projects, especially through sweat equity, offers profound benefits beyond financial savings. While painting walls offers minimal budget impact, participating in tasks like installing hempcrete or clay plaster with friends can significantly reduce labor costs. Sigi highlights the "happy ghosts" phenomenon, where homeowners recall the joyful memories of building their homes with community support. This process not only saves money and gets the job done but also fosters community, connection, and empowerment. These experiences open minds to new possibilities, sparking curiosity and encouraging others to consider more natural and sustainable approaches to their own homes.

Looking Ahead: The Future of Sustainable Living and Natural Building

In the current historical moment, Koko emphasizes the critical importance of natural building in addressing climate change and fostering community. Natural buildings, with their superior insulation, passive solar design, and natural cooling properties, offer resilience against extreme weather and reduce reliance on external energy grids. Beyond environmental benefits, the collaborative nature of natural building provides a powerful antidote to the increasing sense of separation in society, offering opportunities for healing and connection. Our homes, Sigi argues, should be more than just commodities or investments; they should be built capital that pays dividends in quality of life, health, and independence, contributing to a holistic picture of abundance.
