# Lintel · Casa Serra
At first it looks like a flat floor plan of a house. Until you scroll.
**Live demo:** https://sam1983aing.github.io/casa-serra/
**The starter prompt, on its own:** starter-prompt.md
Work in progress, and still in the early stages. It runs best on a laptop. The whole house is drawn in real time, with about 39 MB of textures on a laptop and about 13 MB on a phone. If your device can't run it, you get a still and a clip of the walk.
## How it was made
There is no single prompt. It took about 70 prompts over two weeks and four full versions, with Claude Code and Opus 5.5. It started from a short video of an old game site I liked. The floor plan idea only showed up four days in.
The floor plan is not a picture. It is the real 3D model, cut at 1.2 m and seen from straight above through a very long lens. Scrolling raises the cut, and that is the walls growing. Every room stays a line drawing until the camera gets there.
- three.js, GSAP ScrollTrigger and Lenis. Plain files, no build step.
- Everything you see is geometry made in code. No Blender on this one.
- Textures are free CC0 scans from Poly Haven.
## The prompt I would start with today
It won't give you this page. It gets you a first version of the idea, and then the real work starts. Swap the parts in `[brackets]` for your own subject.
 [code] 
The last paragraph matters as much as the idea. Without it you get a finished page you did not choose.
## What one prompt gives you
I tested that prompt once, on a fresh session that knew nothing about this project. It proposed three layouts and waited. I answered with one line, and about an hour later it came back with a first checkpoint: a plan sheet, walls that rise, and a walk into the first room.

That is one run, so yours will look different. It is a good start. The rest was two weeks of looking at recordings, giving each room a score out of ten, and asking again.
