By designing the interior and exterior, the interior designers from the Prostornina office wanted to honour Plečnik’s legacy. The common thread of the renovation process was upgrading the interior architecture with shapes and materials that respect the cultural heritage of the building. Durable and quality materials such as terrazzo, oak, copper, stone, leather and metal intertwine around the basement with brick-stone walls, massive columns and vaulted ceilings. The basic shape is a semicircle, which is continued through all the area.
