The New York architect collaborated with jewelry designer Rosanne Pugliese on her first retail store. The site was the messy ground floor of a brownstone in Brooklyn Heights. Stripping away cheap finishes, they found original brick walls and oak floors. They further enlarged a window to double as a vitrine for display. At the sidewalk entry, you step down into an inviting store-cum-salon. Warm spot lights showcase the jewelry while drawing visitors in. Deep hues turn rough surfaces and exposed heating pipes into a bas-relief backdrop for Rosanne’s luminous gems and curated objets. A brass beaded curtain screens a small office. Behind that is the artist’s workshop.
