“Should New York City preserve, say, it’s shrinking flower district? What would that mean, practically speaking? Would it mean specialized breaks and subsidies? The flower district is but one of dozens and dozens of business clusters that once defined the commercial geography and cultural identity of the city.” Michael Kimmelman’s contribution to Beyond Architecture on “intangible heritage” had a beautiful spread in the New York Times yesterday. Beyond Architecture is a collection of essays on landmark preservation, construction, housing, and architecture edited by Barbaralee Diamonstein-Spielvogel. The book goes on sale next week.
