Iris Residence: Sustainable Living Crafted from Reclaimed Materials









The Iris Residence, a project by the Denver-based studio Tres Birds Inc., exemplifies sustainable architecture through its creative integration of reclaimed materials. This 2,572-square-foot home in Boulder, Colorado, stands as a testament to environmentally conscious design, repurposing elements from a library and a bowling alley. Beyond its unique material palette, the residence boasts exceptional energy efficiency, achieving a HERS score of 10 and operating as an all-electric, solar-powered dwelling that generates more energy than it consumes. Its thoughtful design navigates challenging site conditions, including a flood zone location, while prioritizing inward-focused living spaces and acoustic shielding from a busy thoroughfare.
Iris Residence: A Beacon of Reclaimed Architecture in Boulder
In a pioneering architectural endeavor, the renowned Denver-based studio, Tres Birds Inc., has unveiled the Iris Residence, a meticulously crafted home in Boulder, Colorado. This distinctive 2,572-square-foot single-family dwelling, nestled on a newly delineated plot of land, reimagines sustainable living by ingeniously incorporating salvaged materials. The home's design journey began with the thoughtful reuse of fittings and lumber from a former library, initially designed by Tres Birds Inc. in 2015 for Shambhala Publications. When the publication relocated in 2021, these invaluable components, primarily constructed from maple plywood, were meticulously preserved and subsequently integrated into the Iris Residence.
Adding another layer of resourcefulness, sections of a bowling alley floor were transformed into innovative shelving units within the home's kitchen and living areas, seamlessly fitting into the gable roof's architectural lines. An oblong dining table, originally fashioned from boxcar train flooring for the client's previous office, now serves as a focal point in the dining space, illuminated by vibrant green pendant lamps. The residence also features a striking two-story library, accessible via a staircase constructed from wood reclaimed from a fire-damaged sugar pine forest, showcasing a harmonious blend of history and innovation.
Situated along a bustling avenue, the Iris Residence masterfully redirects its internal spaces inward, effectively insulating residents from external noise. The design confronted significant challenges due to its placement in a flood zone, necessitating a robust, deep concrete base to meet stringent elevation requirements and local zoning regulations. The exterior, cloaked in a low-maintenance, grey-toned vertical plank siding and a standing seam metal roof, offers both durability and aesthetic appeal. South-facing windows flood the linear interior with natural light, while a protected south-facing courtyard, shaded by double-height columns that extend to form a lanai, provides an intimate outdoor sanctuary.
Inside, the ground floor encompasses a garage at the west end, leading to the library and a guest room, culminating in the primary bedroom on the east side. The upper level hosts the communal living areas and a second guest room, which overlooks the private patio. Demonstrating an unwavering commitment to energy efficiency, the all-electric home achieves a remarkable HERS score of 10, indicating it generates more energy than it consumes. This impressive feat is powered by a 6.2-kilowatt solar panel system strategically mounted on the south side of the roof, complemented by energy-efficient appliances, LED lighting, and a precisely sized Energy Recovery Ventilator (ERV), all converging to create a dwelling that is both technologically advanced and rich in character.
Reflections on Sustainable Design and Resourcefulness
The Iris Residence offers a compelling vision for the future of architecture, demonstrating that luxury and sustainability can coexist beautifully. Its meticulous integration of reclaimed materials not only minimizes environmental impact but also imbues the home with a unique narrative and character. This project challenges conventional building practices, urging us to reconsider the value of existing resources and the potential for innovative reuse. The achievement of net-positive energy consumption further underscores the importance of thoughtful design and technological integration in creating truly green buildings. The Iris Residence is not just a house; it's a statement about our responsibility to the planet and a source of inspiration for how we can build more sustainably and live more harmoniously with our environment.
