Procedural City (2020)

X-Information Modeling

Team: Gunyoung Jang

Cities are living systems, and their true language is data. As designers and planners, we can interpret this spatial data and translate it into more equitable, resilient, and livable environments. By applying computational design methods, we can test and visualize thousands of possibilities, allowing us to focus not only on form but also on performance, human experience, and inclusivity.

This project investigates equality in accessibility, visibility, and safety at the urban scale. The central question is: What if multiple buildings shared a single super podium, and every street intersection was opened to enable people of different abilities to move freely? The super podium becomes a foundation for inclusion—ensuring access for all—while simultaneously providing incentive floor area ratio (FAR) bonuses for towers above, enriching architectural diversity and density.

The design framework explores 256 design spaces, combining variations in grid type (4), FAR options (4), node sizes (4), and podium forms (4). Each option was evaluated through performance-based metrics:

  • Accessibility – proximity of public spaces within a two-minute walk
  • Safety – visibility and openness at street intersections
  • Mental health – daylight availability during colder months
  • CPTED – crime prevention through environmental design, using visual surveillance potential
  • Shadow analysis – assessing the comfort and livability of public ground

Through this process, the research identified an optimized configuration—Street Option 1, FAR Option 4, Podium Height 35 ft, and Node Offset 30 ft—which balances accessibility, daylight, and safety, particularly benefiting people with disabilities.

Design Components

1. Street
- At least four major roads for cars
- Additional bike lanes and sidewalks to ensure multi-modal circulation

2. Nodes

- Converting intersections with a high possibility of collisions into public spaces
- Enhancing safety and accessibility at key crossing points

3.Tower + Podium & Market Hall

- Market halls and podiums on the ground level create highly accessible public areas
- Encourages active pedestrian circulation and shared urban spaces

4. 1F (Ground Floor)

- Ground-level permeability and public accessibility reinforced across multiple buildings
- Supports active edges and continuous public flow

5. Bridge

- At least two bridges per super-podium
- Bridges connect upper levels of buildings to minimize vertical movement
- Strengthens horizontal connectivity between towers

6. Tower
- Upper towers are cut strategically to ensure visibility along pedestrian paths
- Improves CPTED (Crime Prevention Through Environmental Design) by maintaining open sightlines
- Allows more daylight penetration at critical nodes
 

Metric 1: Accessibility
The percentage of building cores that have at least three public spaces within a two-minute walking distance.
Metric 2: Safety
The average percentage of visibly open areas within a 30-foot view range at every street intersection.
Metric 3: Mental Health
The average number of daylight hours during cold months when heating is required is measured for both buildings and streets.
Metric 4: CPTED (Crime Prevention Through Environmental Design)
The number of views from surrounding buildings toward each node, compared to the average number of views across the entire area.
