Turnkey custom home design-build project

Our Custom Home Design-Build Services

Integrated design, construction, resilience, and systems expertise for high-performance custom homes built to last.

Turnkey Delivery

Earth'smart™ Path A aligns architecture, engineering, construction, manufacturer input, and permit coordination into one team from concept through construction for a clearer, more reliable build.

Fire-Hardened Homes

Custom homes are engineered for WUI exposure using fire-resistive walls, non-combustible roofing, ember-resistant vents, defensible-space coordination, and integrated suppression strategies.

Sustainable Luxury

High-performance homes combine refined design with tight envelopes, electrified systems, solar and battery integration, low-impact materials, and water-saving technologies where appropriate.

Fire-Resilient Systems

Earth'smart powered by tect integrates wall, roof, venting, fenestration, defensible-space, fire-water, and suppression systems as one coordinated package rather than disconnected product choices.

Smart Home Systems

Healthy, energy-efficient mechanical, electrical, plumbing, air filtration, automation, leak detection, backup power, and monitoring systems are planned early for lasting comfort.

Advanced Materials

Non-combustible wall assemblies, Class A roofing, mineral wool, steel, concrete masonry, fire-rated openings, and ember-resistant details are specified through coordinated manufacturer input.

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.
