Lloyd Wright’s original drawing of “Typical Triplex Cottage of The City of Mentalphysics.

The Joshua Tree Retreat Center represents the largest collection anywhere of Lloyd Wright mid-century buildings constructed and aligned with Organic Architecture principles. Embodying the essence of Organic Architecture, the interweaving of civilization and human habitation with the natural world, is at the core of this historical space. 

Originally, Ding Le Mei asked Lloyd Wright’s father Frank Lloyd Wright to design the City of Mentalphysics, incorporating nature’s beauty & principles into the spiritual and architectural vision of a “model city of the world and a true city of brotherly love”.  Frank Lloyd Wright referred the project to his son, Lloyd Wright, who already had an established architectural practice in Los Angeles at the time.

Preserving this sensitive land and unique architecture is one of our highest priorities at the Joshua Tree Retreat Center.  As we move forward with our restoration plans we are embracing the legacy of Organic Architecture design principles for this beautiful desert refuge.  To work with us to develop the visioning and design process and help us steward an inspired long-term comprehensive strategy, we formed the Whole Arts Auxiliary and have brought on Design Integration Group (“DIG”) to assist us with the restoration of the buildings and the site and updating an ecologically oriented master plan for the entire site.

DIG’s founders and principal partners, Hannah Wear and Kevin Parkhurst both worked closely with Eric Lloyd Wright, Frank Lloyd Wright’s grandson and son of Lloyd Wright, for over 20 years as Chief Associates in his architectural studio. Hannah and Kevin carry forward the mission of Organic Architecture through their design work and educational programs.  

While with Wright Kevin and Hannah worked towards the evolution of the principles and aesthetics of Organic Architecture with the influence of the insights and concepts of ecological design and our contemporary understanding of social and environmental issues. Kevin was founding Executive Director and Hannah the Program Coordinator of Wright Way Organic Resource Center, a not-for-profit project providing social and environmental education programs based in a rustic 24-acre site in the Santa Monica Mountains above Malibu, California. Hannah and Kevin remain Eric’s and his wife and artist Mary Wright’s personal liaison to the design world.
