Frankfurt is not short of tall buildings, but there’s always room for one more. Müller-Altvatter starts work this month on the construction of the Skyper Project. An office block towering over 150 metres is to be built immediately behind one of the city’s listed buildings. The tower will have 42 floors, including basement parking on three levels. For those not keen on stairs there will be seven lifts, three of them serving the parking garage.
