Built a demo site where the house constructs itself as you scroll — my cold outreach weapon for local home builders

Sharing a win + the playbook in case it helps anyone targeting local businesses.

I picked a niche (custom home builders — high ticket, mostly running 2015-era template websites) and instead of sending a portfolio, I built a full concept demo to pitch with:

🏗️ The demo: a scroll-story website where an empty lot gets surveyed, the plans appear in x-ray, the foundation pours, the framing goes up, and the finished estate lights up at dusk — all driven by scrolling. See it live:

https://heritage-homes-demo.vercel.app

How it was made:

• All imagery + build sequence clips: Claude Fable 5 + Seedance 2.0 (image-to-video with locked start/end frames so the stages connect seamlessly)

• Site: hand-coded HTML/CSS/JS with scroll-triggered animations — no templates, no page builders

• Deployed free on Vercel

• Then used Claude to scrape + research 27 local builders (owner names, their actual projects, what their current sites run on) and write personalized cold emails referencing details like "your footer still says 2015"

The pitch angle that's working: these builders create $3M+ homes but their websites are stock Divi/Squarespace templates. The demo IS the pitch — no deck, no proposal.

Also cut 60s social videos from the site (screen-recorded the scroll ride, edited with ffmpeg, music via ElevenLabs API) for YouTube/TikTok/Reels.
