The School of Constructive Arts is a field school teaching regenerative design, building, and ecology through direct observation, participation, and experimentation. Our approach integrates ancestral knowledge of natural materials and energy with advancing technology and contemporary building techniques to derive sustainable models of living for our time.

We are building our campus in the Big Bend region of West Texas where we are building facilities to support education, research, and experimentation. Beyond this site-specific laboratory for direct study, we are working to bring regenerative design and natural building to individuals and communities beyond our campus. By providing technical expertise, training, building materials, and direct construction assistance we empower our neighbors to build to the highest level of environmental design and construction. To further increase access we have begun to publish media, share research, and compile resources both in a library on our campus and online. In the ‘Learn’ portion of this website you will find the first step towards this open visual library.





The Constructive Arts mission is to empower people and communities to build and live in healthy relation with the land and all its life.
For thousands of years, people have found innovative ways to build and live in harmony with a range of changing environments. Cycles and weather were carefully observed; Water channeled, and soil cultivated to yield food; Wind, sun, and rain were harnessed to heat and cool; Earth, stone, and wood were shaped and utilized in myriad ways. Modern industry introduced new materials, methods, and possibilities, from glass, steel, and concrete to photovoltaic panels and wind turbines. With thousands of years of human experimentation and an array of powerful modern technologies, we have everything we need to build and live in comfort, health, and harmony with our environment.

Unfortunately, we often waste this inheritance, reshaping the earth in ways that are ultimately destructive rather than constructive. In the last two decades 97% of housing built in the U.S. was suburban, mass produced from wood and petroleum products that make people ill, mold, rot, blow down, burn, and require massive electric, water, waste, and road infrastructure. With all our advances, isn’t it odd that the most desirable places to live in our cities are often the oldest, that more and more people seek out fewer wild, undeveloped lands? Pause to look, and it is clear we are building a world that people don’t want to live in. But it is not only built environments that are in decline. Human activity is transforming the Earth more rapidly and dramatically than ever, altering the chemistry of the seas and sky, disturbing essential natural processes, and threatening the balances that sustain all life.

Regenerative design is the study of how to reshape the Earth in ways that are life giving rather than life threatening. It is an ancient art that relies on careful observation, direct experimentation, trial and error. Our ancestor’s lives were intimately bound with place and so they sought not only to sustain but to increase the health of the places they lived. Often they left behind deep organic soils, rich food forests, healthy fisheries, and ecosystems of exceptional biodiversity. By applying modern science to this ancient approach, we too can heal the land and leave pockets of health, diversity, and vitality for our children. We too must start at home, by weaving the patterns of our lives back into the pattern of life as a whole.

At the School of Constructive Arts we work from the ground up, empowering individuals and communities to build durable, healthy, efficient homes from the earth; integrate waste and water systems with natural cycles; and restore soil, hydrology, habitat, and biodiversity in the places they live. To do this we combine hands-on education with direct assistance to change both the perceptions and realities of what is possible. This ‘teach through building’ approach gives students an unparalleled education combining theory with practice. Their work in turn is a gift to future students and surrounding communities. We began by restoring 20 acres of degraded land on the Terlingua Ranch to create a campus and laboratory for direct study. The construction and ecological restoration of our own campus allows us to advance knowledge, methods, and new models through experimentation, trial and error. It is becoming a living example of regenerative design, a place where seasoned experts and students of all ages and backgrounds come to work and study together. Over the past four years a team has come together, along with specialized knowledge, methods, and equipment. In this new chapter we are beginning to offer expertise and assistance to help others build to the highest standards of environmental excellence.

Our Holistic Approach




Ancient and Modern
Technology
Ancestral knowledge of ecology, natural materials, and natural energy is fundamental to regenerative design. Time-tested methods are often more lasting, simple, efficient, and affordable than complex modern solutions. By starting with lean, ancient approaches and selectively integrating powerful modern technologies we can develop more beautiful, durable, affordable, and sustainable models for our time.
Conceptual &Practical Understanding
Education at SCA combines rigorous classroom study with hands-on experience joining theory with practice, thought with action, hand with mind. The divide between mental and manual work is growing. Typical academic study has minimal impact on building practice. Our approach bridges the gap and empowers students with the holistic understanding needed to address the most pressing problems of our time.
Teach Through Building,
Build Through Teaching
Experience based education combines study with service. Students receive the gift of a free education and they give in turn, building facilities and infrastructure to benefit future students. In time we aim to apply this ‘build through teaching’ approach to empower communities beyond our campus. When people work together toward a common good they not only construct buitldings, they build community.
Laboratory for
Innovation
A school is a place where knowledge is advanced not merely passed along. Research and experimentation are fundamental to our approach. Our campus is a living laboratory, a testing ground for new ideas, methods, and prototypes. Flawed methods are refined, successful prototypes become living examples, broadening our understanding of what is possible.

Bob Estrin


Bob is an architect, builder, teacher, and founder the School of Constructive Arts. The son of a builder, Bob’s experience in construction started at a young age. He received his degree in architecture at the Cooper Union in New York City, where he later taught the urban design studio with Diane Lewis. His research on ancient uses of natural energy and natural materials led him to travel to North Africa, an experience that dramatically shaped his approach to design and building. After working on a range of residential and institutional projects in the studio of architect Matthew Baird, Bob received his license and began practicing architecture independently. He founded the School of Constructive Arts in 2020 to carry on research integrating ancient methods with modern building science and technology. With mentorship from Jim Hallock, Todd Swanson, and others Bob developed a detailed earth building curriculum and established compressed earth block manufacturing at SCA. In addition, Bob has developed a comprehensive regenerative design curriculum, bringing his experience and research of advanced natural energy, waste and water systems, community planning, and agro-ecology to the classroom. Bob applies this diverse knowledge to design projects beyond the school, helping others build holistically with the land.

Donald Ray Bryant

May 28, 1925 - Jan 25, 2019



Don Bryant was a teacher, innovator, builder, farmer, and friend to many. Don taught himself principles of structural design and building from books and through direct experimentation. He built many innovative structures on his land on the Terlingua Ranch. Though best known for his ferro-cement domes, he had graduated to adobe and earth-based building by the end of his life. Don would work tirelessly on a project, but when a better idea came along he would shift gears and not look back. Much of Don’s work is unfinished but even so these impressive structures stand testament to his unique vision, spirit, and ingenuity.

Don died in January of 2019 and willed that his land go toward forming a School dedicated to Architecture, Building, and the Environment. The School of Constructive Arts celebrates Don’s memory and carries forward his enthusiasm for building, teaching, and living in harmony with the desert.
