Roof1601 ftAISC: Modern Steel Construction, August 1991

Architect: Eli Attia Architects

This is the tallest building ever proposed by Donald Trump and was to be situated near the geographical center of Manhattan. The tower's geometry is derived from simple but efficient spiral truss framing and a decahedral (10 sided) plan. The telescoping segments of the tower are proportioned by the ratio "phi" (the Golden Ratio of 1.618... to 1) allowing each segment's height to be the sum of the two segments previous to it.

The base was to be an 85' high marble and glass arcade that enveloped the entire block with the rising tower above.

This site is now the location of the Time Warner Center.
