The former suggested name was Solny 4 (the name of the street where the building is located). We decided to use the historical name of Oppenheim-Haus of which the new owners were fond.
We focused on combining the concepts of change, space and new opening and at the same time on preserving the historical legacy of the place.
Oppenheim became OP ENHEIM, OP EN for short. The space after P gives an extra layer to the message and symbolises a new opening: a new space.
