Heliotrope designs smart, contemporary works of architecture that transcend style and trend. Process driven and rigorously attentive to detail, we strive for clear, elegant solutions rooted in a thorough understanding of the social, cultural and physical qualities unique to each project. Powered by fruitful collaborations with clients, craftspeople, consultants and colleagues, the work reflects a passion for people and the various, complex places they inhabit.

Founded in 1999 by principals Mike Mora and Joe Herrin, Heliotrope has been recognized locally, regionally and nationally for their carefully crafted private residential commissions located throughout the West. Heliotrope has also developed a portfolio of highly successful restaurants, retail stores, public spaces and work environments. These projects are informed by a deep understanding of human scale and comfort, developed through decades of residential work, coupled with our passion for creating quality urban experiences.

A winner of eight prestigious AIA design awards, Heliotrope is dedicated to creating spaces and places of enduring quality and timeless beauty.
