The classic alteration and enlargement design of this sixteen-foot-wide townhouse included the construction of a new fifth floor and elevator shaft and stair extension. Interior design finishes, fixtures and materials are all premium architectural grade with exquisite detailing. Natural light is captured with new oversized French doors with transoms and a new skylight pouring light onto the restored sculptural staircase. New mechanical, electrical and plumbing systems provide for a state-of-the-art infrastructure. The totally restored facades and rear yard garden make this a distinctive urban residence.
