16 East 69th Street is a 33ft wide, five story red brick and limestone mansion that stands as a superb example of Neo Georgian revival architecture in America. Prominently positioned on the very lovely and quiet tree-lined block of 69th Street between Fifth Avenue and Madison Avenue, the residence has the good fortune of being situated amidst a number of architecturally noteworthy neighboring houses. Erected in 1881 by Charles Buek & Co. and then purchased in 1900 by Alice Gwynne Vanderbilt, the house was redesigned in 1929 for Edwin C. Jameson, a prominent insurance executive, and then finally acquired by the English Speaking Union in 1956.    It is an architecturally wonderful and immensely charming house with tremendous curbside appeal. Moreover the grand yet understated interior is extremely well suited to major entertaining as well as a cozy and modern "at home" lifestyle. The generous proportions of the house are imminently livable and welcoming, yet the architectural grandeur of the residence remains very much intact due to the masterful renovation work.    Elements such as the broad and graciously ascending staircase, the black and white marble entry floor, and the many period moldings lend the house a quiet dignity. Additional noteworthy features include soaring ceiling heights, 5 woodburning fireplaces throughout, a beautifully landscaped Garden, two terraces, a large state of the art elevator from the basement to each floor, a wine cellar, a private gym and a sophisticated alarm/security system with digital video recording and remote web access.    The acquisition of this magnificent triple mint condition residence affords a marvelous opportunity for the most discerning buyer to acquire a residence of unparalleled luxury and historic designation nestled in the heart of the Upper East Side.    Co-Exclusive.
