In some respects the owners of this San Francisco home, clients of interior designer Melissa Warner Rothblum, aren’t your stereotypical newlyweds. After all, their first home together is a 4,000-square-foot manse in Pacific Heights. But in other ways, they fit the vision of young just-marrieds perfectly—as in, they were willing to have fun and take risks with their new pad. Although the architecture of the house is traditional, the couple wanted interiors that are polished without being stuffy. Their designer presented them with bold choices and strong colors, and they embraced the options to create a home that is stylishly surprising.
