Natural Architecture
fuentesdesign is a small architecture firm committed to transitioning the built environment from the use of fossil fuels to all electric, solar powered buildings. We believe that form follows this function and through this, we seek to create a warmer brand of modernism that results in a genuine feeling of home.
With over 100 architecture projects completed in and around Boulder since 1999, fuentesdesign has worked with the most progressive green building methods and systems since its inception.
We believe that architecture is a fundamental part of the climate change solution.
Our work has taken us from Boulder to Denver to Moab, Durango, Carbondale, Leadville and the high San Juan Mountains. Our design philosophy is based on translating our client’s vision, resulting in stylistically diverse projects that represent the tastes of individual clients as far as layout and aesthetic. However, the unwavering factor in our work is the commitment to the quality of the building structure, indoor air quality, energy performance and personal comfort. We believe architecture must leave a legacy of true value for the owner, inhabitant and society at large in terms of health, ecological repair and energy generation.

“I don’t think we cared about sustainability but that’s one thing that’s remarkable about Brian; he’s very passionate about this and very infectious. He told us from the get-go that was what he was going to incorporate in his designs….the fact that this home produces more energy than it consumes, is amazing….it’s just simply thinking about the way things are constructed differently.”
In over 20 years of designing homes and public spaces we have realized environmental performance does not limit design but rather informs and adds depth and meaning to architectural form. Perhaps the greatest challenge of our civilization will be the reckoning of architecture and human design with laws of physics. Just as the arch represents a triumph of masonry over gravity physically and visually, so does the solar panel integrated with the highly efficient building envelope, heat pump technology and thermal bridge free construction represent the new understanding of global physics and how to keep the world safe from a climate perspective with intelligent architecture.

We believe that the best architecture is not mere aesthetics, it’s an ethical belief that design can make the world better for all.

“I don’t think we cared about sustainability but that’s one thing that’s remarkable about Brian. He’s very passionate about this and very infectious. He told us from the get-go that was what he was going to incorporate in his designs….the fact that this home produces more energy than it consumes is amazing….and I don’t believe there was a huge additional cost, it’s just simply thinking about the way things are constructed differently.”
“Quality is worth the wait. That’s the reason Dan and Pam Harvey did their homework when they found themselves in a position to build a house from scratch. Like any good astrophysicist and neuroscientist, respectively, they delighted in details as they began combing through Boulder’s talented cache of architects. But their criteria stretched beyond someone who could design a zero energy house; they wanted someone who would also put heart and soul into a space intended to last hundreds of years. Young but experienced in sustainable design, Brian Fuentes got on their radar. “We thought since he was younger, he’d put more effort into the project,” says Dan, “That proved to be true.” A prime example was the afternoon the skies opened up, dumping rain on Dan and Pam’s newly poured foundation and metal decking. There was Brian, getting soaked as he pushed excess water off the foundation with a broom.”
“We had an incredible experience with fuentesdesign. When we first met with Brian he explained the Design Build process and passive house model to us and we were sold. Meeting with Brian, Megan and Steven during the design phase was totally stress free, fun, casual, yet very productive. Brian was witty, skillful, and intelligent in handling our random requests and understanding our style while still staying true to what it takes to build a very beautiful and extremely energy efficient home. During the demo and remodel phase we had almost daily contact with Steven who handled the all of the contracting and overall project management. If you want someone to get a mind boggling amount of stuff done with ease and stress-free grace this is the man. I was continually amazed at how many details one person can juggle without ever dropping a single thing while maintaining a saintly calm. He’s not just an superior project manager/contractor, he has an eye for design and the same know-how as the best home builders. I’m not blowing smoke. These guys are the real deal.”
