A method has been developed for automatically generating a phylogenetic tree of architectural plans based on graph theory, according to the properties of the plans and the timing of their appearance. A phylogenetic tree of architectural plans is a branching diagram that shows transitions of the architectural plans by period. In previous studies, researchers analyzed structural similarities and differences between architectural plans by comparing one floor plan to another. Such manual classification processes sometimes result in inconsistent classifications and are inefficient, especially when a large number of plans are compared and analyzed. In this paper, a new algorithmic approach is proposed, termed the time-based joining (TBJ) method, for quantitatively evaluating structural similarities between architectural plans and creating a phylogenetic tree of the analyzed architectural plans. The validity and consistency of the TBJ method's results were tested by generating a phylogenetic tree of 422 collective housing unit plans in Seoul, South Korea, constructed from 1970 to 2010.
