  • About

    We’re inspired by great design every day.
    Our studio is the perfect setting for inspiration and creativity.
    Taking an abandoned car dealership, we turned it into an eye-catching, LEED certified building, with our studio occuping approximately 10,000 square feet.
    Our Des Moines architecture firm is proud to show it off as a demonstration of our capabilities in adaptive re-use buildings. Pay us a visit and we think you’ll be inspired, too.
