This 1870’s brick townhouse was purchased by dealers of contemporary art, with the intention of preserving the remaining historical qualities while creating a comfortable and modern home for their family. Each of the five floors has a distinct character and program, unified by a continuously evolving stair system. Custom built-ins lend character and utility to the spaces, including cabinets, bookshelves, desks, beds, benches and a banquette. Lighting, furnishings, fabrics and colors were designed collaboratively with the home owners to compliment their art collection. photo: John Horner
