This week’s Burning Down the House is a potpourri of news and thought from across the spectrum of architecture and design. Curtis begins with a tribute to the late great structural engineer Ysrael Seinuk, who taught at Cooper Union, the alma mater of Curtis and fellow architect Jacob Alspector, our guest this week. Next Curtis and Jacob (alspectorarchitecture.com) discuss the ever changing skyline of NYC, touching on the history of the Empire State Building and the future of the Vornado Real Estate Trust building. The Plaza and Pennsylvania hotels plus (the original) Penn Station also come up in this discussion of buildings new and old, good and bad, within the fluctuating world of NYC’s built environment.
