Mistake? The owners hired an office architect to build their house, rather than a proper architect who knows houses. Some architects operate well in designing both residential and commercial buildings. Not this one.
Takeaway? Hire someone who has proven themselves to be successful in the area you need help — not the field you’d like them to be successful in. (There is, of course, a place for giving people experience. But not in every arena. I’d hate to have an amateur do bypass surgery on my heart.)
I took this photo along the Highline Canal in Greenwood Village, Colorado. The poor quality is due to using my camera phone.
