At Cornerstone Design, our mission is simple – to create meaning and value through design excellence. Ours is the longest-running independent interior design firm in the State of Idaho, and we’re fortunate to have many long-term relationships with clients, partners and vendors. We bring passion and purpose to each and every project, and strive to raise the bar of design wherever we go. Our firm is unique in the wide range of our portfolio. We believe that talented, experienced designers should be able to design a commercial office space, a hotel or a senior living facility with the same sense of creativity and execution.We are a proven leader in sustainability, but in a natural, integrated fashion. As one of the leading interior design firms in the field of sustainability, we walk the talk. In 2007, Cornerstone purchased a commercial building, designed the interior to LEED-CI Gold standards and achieved this certification in 2008. Founded in 1992, our firm has designed numerous award-winning projects. Named a Boise Metro Chamber of Commerce Small Business of the Year Finalist in 2012, Cornerstone also works throughout the United States.
