There can be no doubting that FOUR Frankfurt is currently one of the most exciting high-rise building and urban district developments in Germany. Over the next few years, an extraordinary ensemble of high-rise buildings will be erected on land covering 215,000 sqm, which used to be occupied by Deutsche Bank directly at the heart of the financial metropolis. One of the buildings will tower to a height of 228 metres (748 ft), making it the third-tallest high-rise building in Germany.
