The aim of this study is to clarify the composition of “townhouse type” architecture by articulation and integration of depth. Townhouse type is defined as the house on the site with frontage narrower than depth. At first, we define “vertical void” as the atrium and garden that is what to bring wind and light into the interior space. The compositional forms of townhouse type are defined through the combination of position of vertical void, handling of lighting surface and staircase in the vertical void. As a result, it is revealed that the articulation and integration of depth in compositional form of townhouse is generated by four stage of differentiation, which are established in containment relationship of concentric.
