One definition of genius is the ability to look at what is in front of everyone in a new way, to see inherent value that others pass up. VALUE DEFINEDThree irreplaceable elements define value in a Manhattan townhouse. First, a Fifth to Madison Avenue location as there is no more valuable corridor on the Upper East Side with its immediate access to Fifth Avenue and the 843 acres of Central Park. Second is width and this townhouse features an exquisite 25 feet of frontage. Third is a classic limestone facade in the Beaux-Arts style. This mansion has all three. ARCHITECT'S ROWIn the early years of the 20th Century, this park block saw a major transformation. Brownstone was replaced by shimmering limestone, and Queen Anne by the lavish Beaux-Arts style. New facades and interior designs were commissioned by the finest architects of the time: John Duncan, CPH Gilbert, James Gamble Rogers, Carrere & Hastings, Ernst Flagg, and Clinton and Russell who designed this house, in addition to The Flatiron building and numerous commissions for the Astor family. THE MANSION TODAYUsing The M Group, the previous owner completed a gut renovation extending over several years and the current owners have added exquisite refinements and upgrades in the years following. A complete detailing of all systems is available upon request. This residence contains 19 rooms with 8 bedrooms, 7 full baths, 3 half baths, and 11 working fireplaces. There are entertaining spaces of exceptional beauty and scale with 12'6" ceilings on the parlor floor, elegant private areas, staff quarters, a gym, as well as a wine cellar. The elevatored building contains approximately 11,550 interior square feet including 1,971 square feet in the finished basement and 2,217 exterior square feet including the patio off the breakfast room, the terrace off the library, and a landscaped roof with views toward Central Park. EXCEPTIONAL DESIGN FEATURESThere is an extraordinary curved staircase that ascends upward for five levels and is capped by a skylight enabling light to pour into the building. A secondary staircase is a work of art in wrought iron with walls of glass - an veritable interior sculpture - that affords access to the upper floors while providing a column of light in the rear of the building. The floating main staircase and the interior rear glass stair were intentionally created to bring light into normally darker areas within a large residence. Further, there is a north-facing library that is double-heighted with 20-foot-tall Palladian windows, undisputedly one of the great residential rooms in New York. The library opens to one of the most exquisite terraces with a fireplace. 7 East 67th Street is the most exquisitely renovated mansion available on the market today: with a 25 foot wide limestone Beaux-Arts facade on a notable Central Park block close to Fifth Avenue, this residence exceeds the criteria for irreplaceable value in a New York Townhouse.
