In the morning of July 10, 2006, Dr. Nicholas Bartha, 66, took his own life by blowing up the townhouse he had resolved to live in until his death. The story of marital failure leading to lawsuits leading to the gas explosion is too sad to recount and beside the point of this post. The lot at 34 East 62nd St., on one of Manhattan’s wealthiest blocks, has been empty for a decade. The battle to build anew has pitted preservationists against each other, and exposes the preservation ethos at its worst.The New York Times and The Architect’s Newspaper reported on the battle over the most recent design proposal.The controversy reminds me of the 1845 Greek Revival townhouse in Greenwich Village that was demolished during a 1970 attempt by the Weather Underground to build a bomb. It was replaced in 1978 by a quasi-modernist townhouse of brick, designed by Hugh Hardy in the same style except that its three bays seem to swivel on a vertical access so that half of it swings in on the building facade and the other half swings out. Really quite an interesting response to the site’s history, much more ingeniously creative than might be expected of a modernist. Lovely, in fact.
