A two-story, 4-bedroom family home designed from one message, then changed by chat
This is a real Plan Chat session from October 2, 2026: one message produced the first dimensioned plan, then 2 changes in plain words reworked it. The plans, numbers and renders below are the AI's unretouched output; the change lists are measured by the plan engine, not written by hand.
Final plan: 5 bed · 4.5 bath · 2 stories · 3,246 sq ft under roof.
