Between January and November 2015, the entrance hall, the original hall and the express zone of the Bank were reconstructed. The changes also included the removal of the original railings on the staircases and wall and pillar cladding. In addition to plasterboard partition walls, Trigema Building also installed interior glass walls on site. In order to protect against excessive sunlight, internal blinds are fitted behind all glass facades. In most rooms there are also new tread layers, but also new lighting. The investment costs for reconstruction amounted to CZK 38 million.
