Sustainable Custom Home Builders in Bay Area

Earth'smart powered by tect helps Bay Area homeowners create sustainable custom homes that are healthier, safer, and built for long-term performance. From the East Bay Hills to Marin, Peninsula, and Coastside WUI sites, our Earth’smart™ approach integrates resilient architecture, fire-hardened assemblies, energy-smart systems, and manufacturer coordination so your home is designed to perform for generations—not just pass inspection.

Our Sustainable Custom Home Services

Integrated design, construction, resilience, and performance systems for sustainable Bay Area custom homes.

Turnkey Delivery

Earth’smart™ Path A brings architecture, engineering, construction, permit strategy, and manufacturer input into one coordinated team from concept through construction for clearer decisions and reliable execution.

Sustainable Luxury Homes

High-performance custom homes designed around tight envelopes, all-electric systems, solar, batteries, low-embodied-carbon choices, drought-tolerant landscapes, and long-term comfort without compromising design ambition.

Fire-Hardened Homes

Wildfire-resistant homes integrate non-combustible roofs, ember-resistant vents, fire-resistive walls, defensible-space coordination, and CAL FIRE Chapter 7A and IBHS-aligned strategies.

Healthy Smart Systems

Integrated mechanical, electrical, plumbing, filtration, automation, water, and monitoring systems improve indoor air quality, energy performance, comfort, and operational longevity.

Fire Suppression

Site-scale fire suppression includes dedicated fire water, pumps, vapor-dome perimeter protection, FIREBOZZ® water cannons, and SMARTVALVE® conservation technology coordinated early in design.

Climate Resilience

Homes are engineered across fire, flood, earthquake, and extreme-weather exposure with structural, envelope, water, energy, and monitoring systems designed for 100+ year service life.

Portrait of Bob Habian, AIA, Architect at Tect

Bob Habian

AIA — Founder, Architect and Manufacturer Advisor

Bob Habian, AIA, brings a rare cross-sided perspective to the building industry: he has been a licensed architect specifying products, a building product manufacturer owner selling them, and an advisor to more than 300 manufacturers working to reach architects and project teams more effectively. That combination sits behind everything tect does. On the owner side, Bob leads Tect's Earth'smart™ practice delivering 100+ year homes engineered to perform across structure, systems and envelope for homeowners across Northern, Central and Southern California — homes built to withstand fire, flood and earthquake exposure while minimizing long-term maintenance cost. On the manufacturer side, Bob leads the tect network of nearly 70 participating building product manufacturers and the Manufacturer Resource Hub, helping manufacturer CEOs, sales and marketing leaders, technical leadership and product representatives understand how architects actually choose products, contribute earlier in design, build genuine product-category expertise, form complementary alliances, and make credible human expertise discoverable in search and AI. His consistent argument to manufacturers is that project teams do not need another channel that exposes products — they need trustworthy expertise available at the moment a decision is forming. Bob draws on AIA specification research, anonymized patterns from work across hundreds of manufacturers, and direct experience on both sides of the specification conversation.
