It is one of the stranger developments in the city, but it could also prove to be one of the most spectacular. David Levinson is poised to tear down most, but not all, of 425 Park Avenue—were he to totally demolish the tower, what he could replace it with could be quite a bit smaller, given a quirk in the 1961 zoning that reduced the density of the site, where a rather unremarkable and outdated 1958 tower now stands.
To fix this problem, L&L Holdings, Mr. Levinson’s development firm, tapped 11 of the planets top architects to sort out this challenge. He has now winnowed the designers for 425 Park down to four, according to The Times, with an unveiling expected shortly. All of them are Pritzker Prize winners with a mixed history in the city.
