Some of New York's most complex construction happens behind closed doors, inside private homes. Here are four examples, and the specialist builders who delivered them.

Each presented a different kind of problem: a landmark shell, mixed trades in one room, a historic district and a new building rebuilt to a higher standard.

Notable Projects

Sky House, 150 Nassau Street

New York, NY

Built by SilverLining, Inc. A 6,500 square foot, four-story penthouse crowning the 1895 American Tract Society Building, designed by David Hotson with interiors by Ghislaine Viñas. An 80-foot stainless-steel slide runs down through the levels. Planning and construction took more than five years, and Interior Design named it one of the best interiors of the last 20 years.
