In retrospect, One57’s introduction to the Manhattan luxury real estate world was no different than a young aristocratic woman’s entrance at her débutante ball. In both instances, the occasion marked the party’s admission as an established member of an elite community. While One57 in Midtown West isn’t formally expected to open until sometime in 2013, the 90-story mixed-use tower atop the future site of the Park Hyatt Hotel is already the name on everybody’s lips. Upon completion, One57 will boast over 135 residential units for sale and layout options ranging from one to six bedrooms. The flexibility offered at One57 will cater to the lifestyle of the most independent New Yorkers and to the needs of growing Manhattan families.
