Loft

The building was built in 1910. "It’s a pretty raw space with rough exposed brick, barrel vaulted ceilings, original hardwoods, and exposed ducting," Greenawalt says. "We tried to use industrial materials—stainless steel, perforated steel, brick—in a more refined way for the kitchen."

This New York City home is studded with pieces by such famous names as Knoll, Saarinen, and Risom. Deployed throughout the loft, these modern icons at once unify and separate work and life. Like the architecture, they can be read two ways: as recognizably typical office furniture or as prized home-design collectibles.

Designer Paola Navone transformed a 200-year-old factory in Umbria into an inviting home for Andrea Falkner-Campi and her husband. Once a tobacco-drying plant, and before that a silkworm farm, the home sits 90 miles north of Rome.

The Tower House is made up of tiny houses, clustered at the southern end of the property and clad in white steel panels and western red cedar shingles. Spinning off the living room on the north side of the main house, the children’s study sits separate from the other pavilions. On its upper level, Oxley netting forms a web on which the kids and their friends can sit and read with views of the leafy street and garden.

The 1920s building was converted into lofts in 2000. The client started out looking for new cabinet hardware and an improved connection between the laundry room and the guest bath, but ultimately decided to work with the firms on a full overhaul.
