Rapid City

Rapid City is an algorithmic experiment that uses parametric conditions to support spatial-configuration development. The site lies beneath the viaduct of the Taichung Railway Line, forming a public void that serves local citizens. The project aims to build a multi-store park that offers renovated public spaces and reconnects the neighborhoods separated by the viaduct.

Phase 1: Defining Connectivity

In Phase 1, the primary goal is to define the value of connectivity. In Taichung City, the street network was established in the early 20th century. The number of intersections reflects the scale and density of surrounding neighborhoods. Therefore, this project adopts a methodology that collects intersection counts within zoning areas along the main streets to evaluate the degree of connectivity.

A 300-meter-radius circle was drawn around each intersection in the road network. Intersections located within this radius were recorded as having a degree of connectivity with the central node. Consequently, intersections surrounded by a greater number of nearby nodes indicate a higher level of connectivity density.

Spatial Formation

The points of intersection from the zone near the main street are visualized into a series of filet polygons. These polygons serve as prototypes for spatial formation. After being rescaled from the urban dimension to the living scale, the shapes are aligned along the viaduct, generating a sequence of interconnected curved plate spaces that reflect the underlying connectivity density of the street network.

Phase 2: Architectural Translation

In phase two, the main goal is to optimize the results from phase one and transform the geometric objects into architectural elements. The parametric process translates abstract connectivity data into tangible spatial experiences, creating public spaces that respond to the urban fabric's inherent logic.

Urban Reconnection

The final design creates a continuous park system beneath the viaduct that serves as both infrastructure and public amenity. The curved plate spaces provide shelter, gathering areas, and circulation paths that help reconnect the neighborhoods previously divided by the railway infrastructure.
