Located in a Victorian Gothic redbrick pile that has had former lives as a convent and a rehab center, this New York pied-à-terre boasts a soaring great hall which still bears details from its past as an Episcopal chapel. The design pays homage to the structure’s bones, with art and furnishings by Andy Warhol and Marcel Wanders, alongside nods to fashion potentates like Chanel, Prada, Fendi, and Gucci.
