The brief
Nanta Alta is a development of 25 mountain villas in Els Cortals d'Encamp. The sales team needed a site that makes the site plan, the typologies and the numbers easy to understand from a phone, in the buyer's own language.
The challenge
The site has to carry a seven-figure purchase on a phone screen, in six languages: the site plan, floor plans, prices and availability all had to stay readable at that size. And every brochure request had to reach the buyer in their own language and the sales team with enough context to follow up, even if an email failed.
What I built
The site is organised around an interactive master plan: pick a plot, see the typology, open the floor plans and the price list. Every brochure button sends the buyer a branded email in their language and alerts the sales desk, with a copy in the team's leads sheet. Guides on financing, residency and buying in Andorra answer the questions that usually come next.
Inside the build
The parts that do the work
01Master plan and floor plans
A layered site plan with a colour key per villa type. Floor plans grow from their thumbnail and zoom with pinch, pan and double-tap.
02Price list with Early Bird
Standard and Early Bird prices for Phase 1, availability per villa, and a count of the Early Bird places still left.
03Brochure in six languages
One form behind every brochure button. The buyer gets a branded email in their language; a repeat request within 10 minutes isn't sent twice.
04Lead capture and sales alerts
Every request is saved first. The sales desk sees who asked, in which language, from which button, and whether the email went out.
05Consent-gated ad tracking
The Meta Pixel loads only after marketing consent, and brochure requests count as leads for the ads. Vercel Web Analytics is cookieless.
06Six languages, prerendered
English, Spanish, Catalan, French, Dutch and German, each rendered to HTML at build time with hreflang, so search engines and link previews see real content.
Recreated with demo data — no real client information.

Visuals & 3D
The 3D behind the sales
Beyond the website, I rebuilt the villas in 3D for the sales films and ads.
Villa 01A in 3D
The 315 m², three-level villa rebuilt in Blender from the architect's plans, every wall, slab and stair to size.
Plan to model
The plans rise off the sheet and the three levels lift apart, in one continuous camera move.
Launch films
A villa film and a blueprint film for Meta, each in 4:5, 9:16 and 16:9.
On the sales site
The same model can be explored on nantaalta.com.
