JAY’S REQUEST

Build a treehouse that works in real life.

Quick start Choose a building part, drag the 3D model, then test it with Jay, Kay, and Elle.
DESIGN REVIEW · ROUND 1

Three ways of seeing the same building.

Nobody has the whole answer. Choose a concern to work on, then revise the model.

Test all three perspectives to begin the debate.
HOW TO PLAY

Build a good idea, then let it be questioned.

  1. 1 · ChoosePick a building part in the tool rail. Its exact controls appear below the 3D scene.
  2. 2 · ShapeWith Room or Roof selected, drag directly on the model. Use the rotate buttons to inspect another side.
  3. 3 · TestAsk Jay about use, Kay about structure, and Elle about order. Their questions update as you work.
  4. 4 · ReviseUse the concerns as clues, not grades. Re-test after every meaningful change.
WHAT IF? LAB

Change the conditions, not the design.

Architecture has to work on more than an ordinary day. Choose a surprise and test your current treehouse.
YOUR CREEKSIDE

The town remembers what you build.

Year 1

Every chapter is open. Pick any project in any order. Later projects can still change earlier ones—the town is one connected system.

Jay’s Treehouse is part of the town.

You brought use, physical reality, and organization into one design. That is architectural thinking.
