The main living area appears to open and close, which reproduces a similar experience as when walking through a forest. A forest light shines through the undulating screen that forms the wall between the bookcase partitions of the library and the ceiling to further imitate the experience of being outdoors. Upon exiting out of the front door, one is submerged in a row of these columns, which are placed specifically by Aalto to emphasize the continuity found between the environment of both inside the villa and out.
