Interior designer Gillian Dubin and her husband, civil rights and criminal defense attorney Josh Dubin, feel a deep connection to Brooklyn. The couple has not only lived in the borough for the past 20 years, but Josh comes from a long line of Brooklynites. “My great-grandfather was a tailor in East New York, and my grandfather was a photographer in Flatbush,” he says. “I’ve always been fascinated by the history of Brooklyn.” When he and his wife began searching for a new home in Park Slope, they were drawn to a brownstone from 1903, the kind of construction that gives the neighborhood its quintessential residential charm. “The house was not in good shape—it had been converted into three units—but it maintained most of its original details, and I really appreciated that,” says Gillian, who established her namesake design studio three years ago.
