The two sketches i decided to base my model on had, on top, reconstruct as its inspiration, and below, confrontation as its inspiration. The model above ground has brick walls and big glass windows, as well as steel structures out the side. The stairs and door have also been made from steel to give the building a sense of continuity. The model below ground has concrete walls to reinforce the walls from the surrounding ground, wooden floors and stairs and steel shells to create the "rooms". The steel is the same as above ground, again to create a sense of continuity throughout the building.
