Frequently Asked Questions

What types of projects does Lincoln Lighthill Architect work on?

Lincoln Lighthill Architect is a full-service residential and commercial architecture firm. Our work includes custom homes, renovations, additions, kitchens, bathrooms, tenant improvements, institutional projects, and bespoke millwork. Each project is tailored to the site, the client, and how people actually live and work.

Where is the firm based and where do you work?

We are based in Mill Valley, just north of San Francisco, and work throughout the Bay Area, California, and select projects across the U.S. Our experience spans urban, suburban, and hillside contexts, with a strong understanding of local planning and permitting environments.

What is your design philosophy?

Our work sits at the intersection of modernism, sustainability, and human well-being. We focus on clarity, proportion, daylight, healthy materials, and long-term performance. The goal is architecture that feels timeless, functions beautifully, and improves daily life rather than following short-term trends.

What makes Lincoln Lighthill Architect different from other firms?

Founder Lincoln Lighthill is a licensed California architect with over 30 years of experience and a background that includes architectural lighting design, sustainability, and high-performance building. He is a LEED Accredited Professional, Certified Passive House Designer, and member of the American Institute of Architects. This combination allows the firm to design spaces that are both visually refined and technically rigorous.

Do you focus on sustainability and healthy building design?

Yes. Sustainability and occupant well-being are core to our practice. We regularly integrate energy-efficient strategies, durable low-toxicity materials, passive design principles, and careful detailing that supports indoor air quality, thermal comfort, and longevity. We believe sustainable design is simply good design done thoughtfully.

Do you offer a consultation before starting a project?

We do. We offer a complimentary feasibility call to understand your goals, site conditions, budget range, and timeline. This conversation helps determine whether we’re a good fit and what the most productive next steps should be before moving into design.

What does the design process look like?

Projects typically move through several phases: discovery and feasibility, concept design, design development, permitting, and construction coordination. We guide clients through each phase with clear communication, defined deliverables, and close collaboration with consultants and builders.

How long does a typical project take?

Timelines vary depending on project size, complexity, and permitting requirements. Smaller renovations may take a few months from design through permit, while larger custom homes or commercial projects can take longer. After the initial consultation, we provide a realistic timeline based on your specific project.

Do you handle permits and work with contractors?

Yes. We prepare permit drawings and coordinate with local jurisdictions as required. We also work closely with general contractors, engineers, and specialty consultants to help ensure projects are well-coordinated and built as intended.

How are fees structured?

Fees are based on project scope and complexity. After an initial discussion and site review, we provide a clear proposal outlining phases, services, and fees. Our work is an investment in design quality, long-term value, and a smoother overall building process.

How do we get started?

The best way to begin is to contact us to schedule a feasibility call. We’ll discuss your project, answer questions, and outline a clear path forward that makes sense for your goals.
