Thomas Rettenwender

M.A., M. Arch., LEED AP, Architect
Founder, Principal

Thomas is a licensed Architect and educator based in Seaside, CA since 2007. Over the past 15 years he has become a leader in providing innovative design solutions for local development challenges.
His studies with Architects Zaha Hadid, Greg Lynn, and Coop Himmelb(l)au at University of Applied Arts, Vienna, Austria, (M. Arch. 2003) and Southern California Institute of Architecture (SCIArc) in Los Angeles, taught him the skills to deliver signature architectural designs that incorporate, in particular, the flow of the landscape and the movement of the body through the built environment. His professional work with local legends Architect Mickey Muennig, Ecologist Paul Kephart have informed his work with a signature ecological design vocabulary born out of a love for our central coast and its unique ecological potential. His work with internationally renowned Architect William McDonough and Scientist Amory Lovins of the Rocky Mountain Institute have informed his work with a smart and resource efficient approach to his design work.

Since 2009 Thomas has been an instructor at UC Santa Cruz, where he teaches the Tiny House Design Lab – a Project-based learning design/build workshop which is part of the new UCSC Sustainability Minor Degree. In the past he has also developed curriculum and taught at local institutions including Monterey Peninsula College , Rancho Cielo Construction Academy, San Jose City College and Hartnell College teaching subjects relating to ecological building design, sustainable master-planning and smart systems.

In 2018 Thomas completed the publication of the Zero-Net Energy Tiny House Manual – a 90 page, grant-funded project through the California Workforce Development Board. This publication serves as a text book for designing extra small portable spaces which can provide housing and off-grid zero-net energy utilities. The publication includes several prototype Tiny House projects and designs that Thomas completed together with local institutions and his students.
