01 / GEOMETRY
The Hat monotile provides the starting geometry. Its wider family reveals how small changes reshape an assembly.
a = 1 · b = √3
a = 1 · b = 1
a = √3 · b = 1
02 / CURVATURE
Joint tolerance accommodates curvature while keeping the same standard component.
03 / GROWTH
Choose an edge, match a unit, check the fit, then extend the boundary.
Find the next active boundary.
Check local edge geometry.
Transform the unit and reject collisions.
Update the inventory and open edges.
If no candidate fits, close that edge and continue elsewhere.
04 / ANALYSIS
Comparative finite-element studies examine lateral response and constrained dilation.
Both response panels use the source figure’s stress scale. These are comparative simulations; prototype assembly is not a physical load test.
05 / MAKING
A 1:10 printed prototype is followed by a 1:1 CNC-milled dry assembly.
06 / SPACE
Atmospheric studies explore light, landscape, and the spatial presence of the system.
AI-assisted concept visualizations. These two images are spatial studies, not records of a built installation.
