This composition is essentially about diagonal lines in modern architecture.
The Toren op Zuid (aka KPN Gebouw) by Renzo Piano has a façade with an overhang of 6°. The single external pole is for the required extra support. The foreground on the left is part of the nearby Erasmus Bridge.
Nearby there is a new high-rise residential building (“New Orleans”) and cranes for the next high-rise project (“De Stad Rotterdam”). Some viewers complained about the distracting cloud “coming out of” the building. The Dutch Photography Museum is incidentally housed somewhere below the green loft on the right.
