The construction work inside the Omega house is progressing rapidly. The first ceiling installations are currently being assembled in the area of the future aisle cladding. This already gives an idea of how the new ventilation system supplies the individual office areas via the central corridor. The vertical ducts that carry the supply and exhaust air over the individual floors can already be seen on several levels. The demolition work in the building component C is still progressing. The construction progress can also be seen on the outer shell. The old structure was removed from the first roof to give space for the new extensive green roof.
