Bank of America Tower – New York, USA

Despite being designed by COOKFOX Architects to be one of the worlds most environmentally efficient and friendly buildings on earth, the 1,200ft tall mega-structure boast an incredible 36% of total non-occupiable height. Thats 1 tad bit more than one-third of the entire building.

Zifeng Tower – Nanjing, China

 Being aptly named on their website as “GREEDLAND PLAZA/ZIFENG TOWER”, the vanity in the building is no surprise. Despite providing its visitors with glorious views of the city, the 1,480ft tall tower is the first to hit our 30% mark with the upper portion of the tower being non-occupiable and entirely put to waste.
