The Sage
A sustainable demonstration home for the 2009 HBA Tour of Homes that achieved LEED Platinum, Earth Advantage Platinum, and an Oregon High Performance Home rating.
Location — Eugene, OR
Year Completed — 2009
This was our first LEED-certified project. We took a three-fold approach to our decision making to achieve a balance of sustainability, architectural aesthetic and economy. Challenged with a very small, reclaimed site, we designed The Sage to maintain solar access to adjacent properties, to provide privacy for our neighbors by the careful placement of windows, and in general, to not overpower the site.
Sustainable Features:
- drought-resistant landscaping

Zero VOC paints were used throughout the house, as well as no combustion appliances, passive ventilation, the highest quality air filters, heat recovery ventilator to ensure fresh air exchange, and third party testing for accountability.
