Gabriel Keller and Lars Peterssen, AIA, started their residential-focused firm just less than three years ago, renting space from Elness Swenson Graham Architects. The next stop for Peterssen/Keller Architecture was this—the firm’s own 2,000-square-foot space. “We knew we wanted to be in Uptown because of the potential for work,” Keller explains, referring to the affluent residential neighborhoods nearby.

Once a warren of rooms with a drop ceiling and firebrick everywhere, the office now showcases exposed steel columns, a renovated kitchen, and a terrazzo floor. At the entrance, the partners designed a comfortable, relaxing area “with a nice residential feel,” Keller says. Translucent panels separate some of the areas, red cord fixtures articulate the space, and wood recovered from a grain silo’s interior adds rustic warmth.
