Mismatched architecture is defined as architecture whose current situations don’t match their original settings during transformation. This mismatch manifests itself as a mismatch in form, function, and context, among others. Mismatched architecture is a self-adapting process of architecture and society, it gives us an insight into the collective memories of the neighborhood.

Architecture and landscape in the urban environment are often the results of a mixture of economic, political, and social demands, and they sometimes grow into mismatched architecture when the demands gradually change over time. Sometimes mismatched architecture brings chaos and confusion, but “…in exchange, it contains a quality of freedom for production” (Kaijima, Kuroda, Tsukamoto, 2006). They are mismatched but fit.

For architectural designs, the question is, how to use the mismatched characteristics to create productive spaces?
