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."

A social creature who seems to know everyone, Loft J occupant Jamil Malone has hosted several "alcohol-themed" parties and manages to wedge as many as 20 people into his studio. The gatherings are like gallery openings, with the walls of Malone's apartment displaying a roving selection of locally produced art.

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.

Uninterrupted cement flooring was chosen for the mezzanine. The cement extends to the bed and bathtub block, while the exposed ductwork and black beams above dramatically accentuate the ceilings.

Futuristic floating stairs lead to the loft’s mezzanine. Throughout the lower level, natural stone was chosen for the flooring, laid at an irregular angle to add visual interest.
