About Texas cob co

TEXAS COB COMPANY was founded by Simon Gonzalez and Arielle Crawford through a motivation to bring industry legitimacy, accessibility and modern appeal to natural building.

Together they have helped bring these ancient modalities back to contemporary awareness, resisting the convenience of synthetic materials for the integrity of earthen elements and artisan craftsmanship.

Simon and Arielle enjoy the process of building from the land - utilizing local ingredients such as clay, sand, stone, and even cactus and cow patties - for their contract work across Texas. Environmentalism, personal wellness, self-sufficiency and primitive skills are a core part of their work.

They regularly host workshops and online educational content through their nonprofit, THE REALNESS PRESERVE.
