As its name says, this architecture is designed to be placed in the “interstice” of the city, which can be not only in the physical gap between the buildings, but also in the culture. The building is narrow and long, but having all the elements that a house has. As a high-tech modular house, it can reuse some special narrow plots, this will both enhance the utilization of land in developed cities and mitigating housing problems. What’s more, these houses can enhance the economic value and cultural value of the area, and achieve the rejuvenation of urban areas in the post-modern era.
