About DPO Construction
Welcome! I’m Don Otto, owner of DPO Construction LC, and now celebrating 31 years of building environmentally friendly homes. Beginning with building Iowa’s first 5-star energy rated home, I have continually researched, developed and incorporated cost-effective, energy efficient techniques in my construction business. This site is organized into three general categories:
- Learn more about my efficient home building courses and register.
- Take a look at the news articles about DPO Construction.
- View a gallery of completed projects.
- Read documents on how I build.
- Images of why building green is important.

“You know you have reached perfection of design
not when you have nothing more to add,
but when you have nothing more to take away.”
