125 Lincoln Street redefines a key edge of Boston’s Leather District with a 14‑story life‑science building that bridges the neighborhood, Chinatown, and the Rose Kennedy Greenway. The design introduces pedestrian‑oriented plazas, activated retail, and a facade that reinterprets the area’s masonry context: a solid six‑story base, setback “zipper” floor aligning with the historic street wall, and a lighter glass volume above.
