When digital advertising agency IMM outgrew its offices in downtown Boulder, Colo., they decided to relocate to the industrial Flatiron Park on the city’s outskirts. The agency enlisted OZ Architecture to transform their new space — a vacant warehouse — into “a unique office environment that would excite their employees.”

The finished project, both sleek and spirited, fills with natural light from its floor-to-ceiling windows and skylights. Biophilic design elements like in-office plants and several outdoor spaces, as well as quirky touches like a millwork sculpture that doubles as a tech-free meeting room, give the new office both an air of creativity and of calm.
