Carter Horsley's Review

Carter Horsley's Building Review
"Some architects like to recycle their plans, but not Norman Foster, Lord Foster of Thames Bank, the architect of such major world landmarks as the Viaduc de Millau Bridge over the Tarn Valley in France, the very high-tech Hong Kong & Shanghai Bank tower in Hong Kong, the Sainsbury Center in England, the glass dome at the Reichstag in Berlin and the glass roof at the British Museum in London, and the Hearst Tower on West 57th Street and his very slick 50 United Nations Plaza with some curves now nearing completion for the Zeckendorfs here.

His latest project is a mid-rise apartment building for SR Capital of which Scott Resnick is the principal and GTIS Partners at 551 West 21st Street in Chelsea, just up the proverbial road from Jean Nouvel’s crazy-quilt 100 Eleventh Avenue and Frank O. Gehry’s billowing office building for Barry Diller’s IAC building.  Mr. Resnick was formerly president of Jack Resnick & Sons and is the chairman of the Building Committee of the Whitney Museum of American Art that is relocating from Madison Avenue to a new building designed by Renzo Piano in the Meatpacking District by the High Line."
