Built with steel-frame construction, Olerra Flex-Flats are exceptionally durable—resistant to 165 mph winds, rated for 1-hour fire resistance, and designed to support 105 lbs of snow and wind load. With spray foam insulation for energy efficiency, our steel frames offer a sturdier, longer-lasting structure than the wood frames used in traditional builds.
Olerra completes most projects in just 3-6 months—half the time of traditional or competitor builds. Flex-Flats are 90% factory-built in under a month and installed in a day using helical pile foundations. With only final touches like roofing and utility connections left for on-site, the process is smooth and minimizes disruption.

A few words from the people we've built backyard spaces for.
"Shockingly smooth. The Flex Flat arrived 90% done—all the finishes already in place. We watched them crane it into our backyard, and in five or six hours the whole structure was together. All in one day. Pretty amazing to see."
"Olera turned our home into our dream home. We've got this amazing rooftop deck where we watch sunrises and sunsets—the kids even have breakfast up there. It fills a void we had before, giving us the space we always needed. ”
"We were a little worried about whether a new structure in the backyard would clash with our custom home—but the Olerra team helped tie everything together. It feels completely cohesive now, like it was always meant to be here.”
