One early Monday morning a large crane is parked for Concertgebouworkest House in the light of the rising sun. The operator lifts relatively small white bags over the old Berlage building. The small white bags are filled with gravel and they are heavy. The destination is the roof garden. Once a bag has been emptied, it is - waving as a wind vane - lifted back over the soon to be office of the orchestra.
To date, the roof garden has been used as an open-air rubbish hutch, workshop and warehouse. But now everything is changing. The gravel is evenly distributed over the roof. Large planters are filled with soil and young plantings. For the neighbours of Concertgebouworkest House, the roof garden is a visible indicator that the contractor is in the final stage of getting Concertgebouworkest house ready for opening.
