In Jo Coenen’s works, the importance of contextualisation is self-evident. His architecture and his architectonic-urban designs not only fit in with their environment, but are also embedded in them – they absorb, reinforce and reflect the characteristics of their surroundings. The situation with respect to the OBA was quite a different one. A totally new urban development, of which the OBA was the first building to be constructed, is now emerging on the spot where the Central Station post office used to be, of which the high-rise building, known by the name of Post CS, is now the only remnant. Consequently, the library could not adapt itself to an existing context, but had to anticipate its future surroundings. Jo Coenen’s solution has been to search for a connection to what the future context might be, to predict which sensations might be evoked by those new surroundings.
