Text description provided by the architects. One of the most unique aspects of Modern Korean Housing is the balcony space in the apartments. Balcony is an in between space that connects the interior space and the exterior space. Although it plays an important role in experiencing the interior space, balcony has never received a full attention in the discourse of architecture. In most cases, a balcony either disappears as the interior space expands or becomes a meaningless universal space that serves miscellaneous functions. This project takes a balcony not as a bonus space but as an essential element that constructs a house. As a “Voidwall,” it divides the interior space and makes connections between the rooms. Each room has its own balcony, and the house is defined by the characters of the balconies. The minimal element makes the whole.
