Lintel · Casa Serra · Starter prompt
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. Tested once in Claude Code with Opus 5.5.
Starter prompt
I want to build a scroll-driven landing page for [an architecture studio, a house, a hotel, your subject]. The idea: the page opens on a flat floor plan, like a sheet an architect prints. Black ink on paper, room names, dimensions. Nothing looks 3D. When the visitor scrolls, the walls rise out of the drawing, the camera comes down to the front door and walks through [the rooms you want, in order] at eye height. Each room stays a line drawing until the camera gets there, then the real materials sweep across it. What I care about: - The floor plan is not a picture. It is the real 3D model, cut at about 1.2 m and seen from straight above through a very long lens. The drawing and the building are the same thing. - The camera travels deep into the space, room after room. It does not orbit the building from outside. - It should feel like [a house that costs millions, your level of ambition]: big rooms, real furniture, late afternoon light. - three.js, GSAP ScrollTrigger and Lenis, plain files, no build step. Free CC0 materials for the textures. Before you write any code, propose the layout of the building with sizes I can picture, and the camera path stop by stop. Give me two or three directions to choose from and wait for my answer. Then build in checkpoints. First checkpoint only: the plan sheet, the walls rising, and the walk to the first room. Record it and show me before you go further.
The last paragraph matters as much as the idea. Without it you get a finished page you did not choose.
What one run gave
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. That is one run, so yours will look different.
