Lincoln Lighthill Architect is a full-service architectural firm based in Mill Valley, just North of San Francisco where the firm was founded in 2015. We’ve designed a wide range of residential, commercial, arts, institutional, and food service establishments, locally and internationally, and we’re always taking on new challenges.

LLA works at the intersection of aesthetics, sustainability, and healthy building design. We are design-oriented, creating functionally and aesthetically inventive and unique solutions that provide enduring joy and value for our clients. The environmental impact of our work is considered at many scales, benefitting our clients, projects, and the larger world. We prioritize healthy living through the materials and systems we specify, the attention to natural and artificial lighting, and much more.  This approach yields exponential benefits for our clients and the broader community – good for our minds, hearts, bodies, and the planet.

Listening is a key part of our process. Our wide range of work fosters a curiosity about what is exceptional and important in every project, and our clients’ unique needs and desires inspire original, inventive solutions that are uniquely tailored to them.

Along the way, we help these individuals, families, and organizations build buildings and relationships. A construction project is a journey we take together, bringing others aboard as we go, and the final product can only be as successful as the foundations we build before the shovels hit the dirt. We work hard to earn your trust and to leverage the trust we’ve built with other industry professionals to ensure a successful outcome.

To ensure all goes as planned, we provide full architectural services from due diligence and conceptual design through permitting, general contractor selection, and construction observation, working hand in hand with consultants, builders, and makers to achieve the desired result.

What can we help you create?

LLA staff includes registered architects, certified Passive House designers, and LEED accredited professionals. The firm is Certified by the City of San Francisco as a Green Business and a Local Business Enterprise (LBE).
