Frequently Asked Questions
Cob houses offer excellent thermal mass, keeping homes cool in the summer and warm in the winter, reducing energy consumption. They are also environmentally friendly, utilizing natural and locally sourced materials. Cob is fire-resistant, durable, and can be sculpted into unique, aesthetically pleasing designs, perfectly suited for Southern California living.
We use stabilized cob mixes with proper clay, sand, and fiber ratios to minimize cracking and erosion. Our designs include wide roof overhangs and moisture barriers to protect the walls from rain. We also incorporate seismic reinforcement techniques to ensure structural stability in earthquake-prone areas of Los Angeles.
We prioritize locally sourced clay, sand, and straw for our cob mix. We also incorporate recycled materials like reclaimed wood and glass bottles for decorative and structural elements. Our commitment to sustainability extends to using non-toxic finishes and natural plasters, ensuring a healthy indoor environment.
