They say purchasing a home means you have to compromise. Surely you can’t have everything you want. Well, this $18 million opulent apartment in the York & Sawyer-designed 860 Park Avenue would beg to differ. Old world charm? Check. Modern conveniences? Check. Enough architectural details to make the biggest architecture nerd’s head spin? Check and check. This 4th floor unit is the supreme luxury abode, in one of the city’s premier white-glove co-ops, which is exactly what you would expect of a building designed by the same people responsible for the Federal Reserve Bank and the Bowery Savings Bank.
