Sustainable Building.

Designed for your well-being.

Why a Healthy Home Matters.

The average person spends about 90% of their time indoors. The materials and systems we choose directly impact your air quality, comfort, and investment durability.

Indoor Air Quality

Low-VOC Materials
Traditional building materials can off-gas harmful chemicals for years. We specify paints, adhesives, sealants, finishes and even furnishings  that meet stringent low-VOC standards, reducing indoor air pollutants that can trigger allergies, headaches, and respiratory issues.
HVAC Design
While popular mini-split systems are highly efficient, they don't excel at air filtration. We incorporate supplemental air filtration systems to work alongside these units, ensuring clean air throughout your home. Additionally, we properly size cooling capacity for optimal humidity control.
Moisture Management
Hidden moisture can lead to mold, structural damage, and unhealthy living conditions. We use moisture control strategies including proper vapor barriers, site grading, and ventilation in critical areas like bathrooms and kitchens.

Comfort through Building Science

Advanced Building Envelope
By using advanced air sealing and insulation, vapor barriers, and high-performance windows, we create a superior building envelope. Hot and cold spots are replaced with consistently comfortable temperatures.
Natural Light Optimized
Thoughtful window and skylight placement based on lot orientation and room layouts brings in abundant natural light. High-performance glazing blocks UV rays, reduces glare, and manages heat gain.
Acoustic Comfort
Peace and quiet shouldn't be a luxury. Our construction methods include sound-dampening materials and assemblies that reduce noise transmission between rooms and from the outside, creating the serene environment you deserve.

Water

Pure Water On Tap
We offer whole-home or under-sink reverse osmosis water filtration systems, providing clean, pure drinking water directly from your tap.
Smart Water Use
High-efficiency plumbing fixtures and smart landscape design and efficient irrigation systems lower your water use without sacrificing performance. For those that want to take it a step further, we offer stormwater capture and greywater systems.
