BUILT WITH ConcreteCore™ Construction
Every model is engineered for exceptional strength, comfort, and energy efficiency.
Stronger. Quieter. More Energy Efficient.
Every ADU we build is constructed using our proprietary ConcreteCore™ Construction system—designed to deliver exceptional durability, year-round comfort, and long-term value.

Whether your ADU is used for rental income, aging parents, adult children, or a private guest house, ConcreteCore™ helps create a home that's comfortable to live in and economical to own.
What Makes ConcreteCore™ Different?
Reinforced concrete core for exceptional structural strength
Continuous insulation for improved energy efficiency
