820 Park Avenue, ca. 1922.

This Park Avenue building is a glorious reminder of New York's past. It was built in 1927 for the flamboyant publisher of the Hearst organization, Albert J. Kobler, who got his start in the business selling newspaper ads around 1910. Kobler hired Harry Allan, the architect behind the Friars Club and many lavish residential projects, to erect what was then a "modern concept" in apartment living: multiple mansions stacked one upon another.

With time, the duplex and penthouse triplex house that Allan constructed for Kobler has come to represent the last gasp of the old, extravagant ways of Manhattan living. The duplexes, however, have since been divided into single floor-throughs with only a few today that have returned to their initial grandeur.
