one way to see some of the coolest, most innovative and interesting homes in Austin and Round Rock. We hope you find at least one helpful morsel at each site,


whether it be a contractor’s business card, a new product or an unusual use for an otherwise landfill-bound item. Austin Energy Green Building, our co-producer for this event, is celebrating 20 years of educating the public, making connections among building professionals and the community they serve, and demonstrating there is money to be made and saved by building and living sustainably. Texas Solar Energy Society is honored to partner with this award-winning program. If you have any suggestions for us for next year’s tour, we want to hear from you. This is your tour, and we want it to keep our city wonderfully weird and very cool. Best regards,

Natalie and the TXSES team

anyone who would like to build something for the first time.” A metal building kit, found on the Internet, was rescued from a Houston dock and transformed into a home and workspace. Demonstrating local sourcing at its best, she got everything from reclaimed lumber, to mulch from neighborhood limb removal, and transformed this industrial building into a comfortable, energy-efficient home for entertaining and working.

Ask how these homeowners managed construction waste—and find out why it’s important here.

Well-proportioned spaces, soothing color palette, and lines of sight to the outdoors give this five-star home a sense of spaciousness and well-being. The U-shaped design, normally an energy penalty due to the amount of exterior wall, creates a private courtyard without compromising energy efficiency: the third side is a screened room. Over 85% of total construction waste was recycled, much of it onsite. This home replaced a dilapidated eye-sore, prompting neighbors to thank the owners and builder.

The owners, who lived for years on a sailboat, knew the benefits of compact living. Working with a fixed budget, they designed and built this work/live house themselves. Despite wanting a net-zero home, they found that many green technologies were out of their budget. The challenge was to squeeze the most energy efficiency out of their limited resources without sacrificing the details that make the home feel comfortable and spacious. Green Features:
