Tasked with transforming a 93-square-foot brick boiler room into a guesthouse, architect and metalworker Christi Azevedo flexed her creative muscle. The architect spent a year and a half designing and fabricating nearly everything in the structure save for the original brick walls. "I treated the interior like a custom piece of furniture," she says. Photo 1 of 3 in A Compact Three-Story Brick Loft in San Francisco

Architect Christi Azevedo deployed Ikea cabinetry in the kitchen (left), which spans almost the entirety of the renovated building. In lieu of adding standard-issue fronts to the upper cabinets, she created sliding doors of sanded acrylic panels. A PaperStone work top extends from the stainless steel counter for additional prep space. When not in use, the movable dining table—also designed and fabricated by Azevedo—fits snugly beneath it.
