Structure Lab Pick a material and enough support columns so a building carries its load to the foundation — predict whether it stands, then run the load test. 
City Planner Fill a city block so families, shops, and parks make good neighbors — watch happiness and sustainability change as you plan. 
Balance the Block The capstone: four decisions cascade across five systems — there is no free lunch, so keep every system healthy, not just one. 
Street Designer Compose a street cross-section — sidewalk, bike, bus, car, trees — to fit a design goal. Streets are rooms; cars are guests, not owners. All activities

Meet the cast — the characters who teach this
-
Block Zoning + density — the badger-tween with clay-block models who teaches zoning as 'plan for the neighbors first, not the buildings' -
Stoop Public space + community — the capybara-elder on a wooden stoop who treats public space as the city's living room, foregrounding existing stoop-cultures (Brooklyn / Latin American plazas / Italian piazzas / West African gathering trees) -
Lane Walkability + mobility — the rabbit-tween in safety-vest with a chalk-spool who teaches streets-as-spaces ('streets are rooms; cars are guests, not owners') -
Hub Transit nodes — the pangolin-tween in conductor-vest who teaches that transit is about ACCESS, not about cars-vs-trains ('many ways, equal ways; the bus matters as much as the train') -
Dwell Housing equity + repair — the owl-elder in a mended quilted-coat who teaches anti-displacement, repair-not-replace urbanism ('repair before replace; listen before plan; the people who live here ARE the design') -
Canopy Green infrastructure — trees and parks cool the city and soak up rain; shade placed where it is needed most -
Mix Mixed-use land use — weave homes, shops, and work close so daily life is a short walk -
Seam Edges and connection — a highway can rip two neighborhoods apart; design can stitch them back -
Berm Climate resilience — the beaver who builds soft green earthworks that bend and soak up floods instead of walling them out -
Conduit Infrastructure — the badger who tends the hidden pipes, wires, and drains beneath every street
