CUSTOM HIGH-PERFORMANCE HOMES
We design custom single-family homes that feel beautiful, healthy, and innately comfortable—using proven high-performance and Passive House strategies for energy efficiency, superior indoor air quality, and lasting value.
PASSIVE HOUSE &
SUSTAINABLE RESIDENTIAL ARCHITECTURE
At Zimmerman Architecture, we specialize in custom single-family homes designed for comfort, efficiency, and resilience. Our work blends thoughtful design with building science to create houses that are as beautiful to live in as they are efficient to operate. From initial visioning to detailed documentation, we partner closely with clients to make high-performance living a reality.
Why High-Performance Matters
Comfort You Can Feel; Efficiency You Can Count On
We apply Passive House principles—like optimized insulation, airtight envelopes, and balanced ventilation—to deliver homes that:
maintain even indoor temperatures
use significantly less energy than conventional houses
provide exceptional indoor air quality for your family’s wellbeing
Whether or not your project pursues formal Passive House certification, these performance strategies are central to our design process.
