The shell construction work is already in the attic floors. There, the attics are being built; formwork and reinforcement are being installed and concreted. The contours of the future attic floors become visible. Simultaneously, interior work for future serviced apartments begins on the ground floor. The installation of full-height drywall partitions to separate the individual units starts. The entrance door frames are installed, making the access corridor clearly visible. Currently, the necessary ceiling and flank insulation are being installed in the basement. This step is necessary for the thermal and sound separation of the underground garage and the components above. At the BTA, the remaining fall protection measures for the balconies have been installed.
