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.
