From what I can ascertain talking to the friends and family of the late Charles Haertling, the Boulder-area architect was passionately devoted to the natural world and to radical, forward-thinking architecture. His designs blend the two into an organic style totally his own, unabashedly. I wrote a portrait of Haertling and his work for the Archive section of this month's Dwell. I think it captures his iconoclastic dedication to architecture. I couldn't have done it without the help of my lovely and talented friends, graphic designer and artist Laura Haertling (his daughter) and photographer Cody Andresen, who directed me the work and connected me to the rest of the family and to clients. Thank you.
Here is a black and white PDF of the piece, sadly, it isn't online and my copy of Dwell hasn't arrived to get a crisp color version.
Update: now available online!
