Start here

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.
Brain Break Take a quiet moment between plans — a short breather. Brain breaks help you remember what you learn.
