Our Custom Design & Build Services

Integrated design-build services for resilient, healthy, efficient, and long-lasting custom homes.

Turnkey Delivery

earth’smart powered by tect coordinates architecture, engineering, construction strategy, permit planning, and manufacturer input through one aligned delivery model, reducing friction between design intent, building systems, and field execution.

Resilient Homes

Homes are engineered to perform across structure, systems, and envelope, with strategies for fire, flood, seismic exposure, durability, comfort, and long-term lifecycle cost reduction.

Sustainable Luxury

earth’smart powered by tect designs high-performance custom homes with efficient envelopes, all-electric systems, solar and battery integration, healthy materials, water conservation, and refined architectural quality.

Smart Home Systems

Integrated mechanical, electrical, plumbing, air quality, water, lighting, climate, security, monitoring, and automation systems are coordinated early for comfort, reliability, and operational longevity.

Advanced Materials

Non-combustible, long-life, and high-performance assemblies can include concrete masonry, ICF, AAC, steel framing, mineral wool, Class A roofing, and coordinated envelope systems.

Manufacturer Coordination

Through the TectApp™ community of 70+ building product manufacturers, earth’smart powered by tect brings direct product and system expertise into the project before critical design decisions are locked in.

Frequently Asked Questions

What does custom design-build mean for a custom home?

Custom design-build means architecture, engineering, construction strategy, systems planning, and material coordination are aligned under one delivery approach instead of being handled in disconnected phases. That coordination is especially valuable because zoning, site conditions, utility conditions, and permitting requirements can influence design decisions early.

How is earth’smart powered by tect different from hiring an architect and contractor separately?
