The Kostabi World Trade Center was an envisioned building in New York City, United States. Designed by Mark Kostabi in the 1990s, it would have had 160 floors and would have been 2,000 feet (609.6 m) high. It was one of the many ideas for the World Trade Center site. The Floor plates at the base of the building contain more than 200,000 square feet. It was proposed in the late 1990s as the world's tallest building by developer Mark Kostabi.
