Walkable 3D house generated from floor plan

claude opus 5.5 completely solved three.js it took a floor plan and turned it into a 3d house you can walk through home builders pay $5k to $10k per floor plan for this, so buyers can tour a home before it's built and change things if needed here's how to automate client acquisition: > scrape builder sites for plans with no model home > give the plan and their photos to opus 5.5 > it builds the house to scale as a walkable site > send the builder their own plan before you pitch > charge per plan to do the rest of their catalog > rerun it on every new plan they launch give this prompt to your agent to get started: "here's a floor plan and photos for one house. build it as a three.js site i can walk through in the browser, to scale from the plan, with every room, finish and piece of furniture matched to the photos. the bar is the photos themselves. split the house into pieces you can judge separately, and give each one a builder and a separate critic with fresh context. the critic compares a screenshot of our room with the matching photo, picks the better one, names the biggest gap, and sends it back. keep looping until ours wins or i stop you, and tell me anything you couldn't match."
