Resilient custom home design-build project

Our Design Build Services

Integrated custom home delivery for resilient, high-performance, fire-hardened, and future-ready residential projects.

Turnkey Delivery

Earth'smart powered by tect aligns architecture, engineering, construction, manufacturer input, and permit coordination under one team from concept through construction, creating a clearer path for complex custom homes and wildfire rebuilds.

Fire-Hardened Homes

Homes are designed for high-risk WUI conditions with fire-resistive walls, Class A roofing, ember-resistant vents, defensible-space coordination, and integrated suppression strategies that go beyond code minimums.

Sustainable Luxury

High-performance custom homes combine refined design with electrified systems, tight envelopes, solar and battery readiness, low-maintenance materials, water-saving technology, and comfort-focused environmental control.

Smart Home Systems

Integrated mechanical, electrical, plumbing, energy, air-quality, monitoring, automation, leak detection, and wildfire smoke filtration systems are coordinated early for comfort, efficiency, and operational reliability.

Climate-Resilient Construction

Earth'smart powered by tect designs 100+ year homes for fire, flood, earthquake, and extreme-weather exposure using coordinated structure, envelope, water, power, and monitoring systems built for long-term performance.

Owner Representation

For homeowners with an existing architect, engineer, or contractor, earth'smart powered by tect provides owner-side strategic guidance, system reviews, manufacturer coordination, documentation support, and critical decision-making assistance.

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.
