Siska headquarters were designed to feel as a very small neighborhood where different departments and functions of the company are located in separate prefabricated buildings. Plywood and black painted stones were used in the facades of the single-storey building units. All building and certain decorative elements are recycled from the construction projects Siska has completed.
