Case Study | Marmax Realty
From outdated WordPress site to a modern Next.js website with Inmovilla API and Sanity CMS
The challenge
Marmax Realty is a real-estate agency (inmobiliaria) based on Spain’s Costa Blanca, operating in areas such as Alicante, Elche, Altea, Calpe and Javea.
Their previous WordPress website was connected to the Inmovilla CRM but faced clear limitations: slow loading times, an outdated design and very little flexibility.
Many WordPress websites connected to Inmovilla eventually hit their limits in terms of layout customization and property filter options.
As a developer, I’m not bound by those restrictions — using a modern tech stack allows me to unlock much more potential from the same Inmovilla CRM integration.
The result was a standard template that no longer matched the image of a professional real-estate agency on the Costa Blanca.
The client’s request was clear:
“A warm, modern website with large visuals, user-friendly navigation and the freedom to manage content independently.”
The Costa Blanca real-estate reality
Most real-estate websites in Spain look alike: slow pages, cluttered menus and no sense of local identity.
Yet visitors decide within 0.05 seconds whether they stay or leave,
and 53% abandon a site that takes more than three seconds to load.
In a competitive market like Alicante, Moraira and Denia, every second — and every impression — matters.
A fast, modern and well-designed website isn’t a luxury; it’s essential for conversion and credibility.
The approach
I rebuilt the entire website in Next.js 15, with Sanity CMS as a flexible content foundation.
Property listings still update automatically via the Inmovilla API, while all other content — texts, services, blog posts and testimonials — is now managed directly in Sanity.
This gives Marmax Realty full control over their site without depending on external developers.
Tech stack:
Next.js 15 • Sanity CMS • TailwindCSS • TypeScript • Inmovilla API • Edge Caching
The focus was on speed, SEO and trust-driven design for international buyers searching for real estate Costa Blanca, inmobiliaria Costa Blanca, houses for sale Benidorm or apartments in Villajoyosa.
The new design conveys calm and quality — large photography, warm tones and clear calls-to-action.
The site is fully responsive and multilingual (Dutch, English, Spanish).
The result
Marmax Realty now has a future-proof, scalable and lightning-fast real-estate platform:
- Multilingual (EN / NL / ES)
- Real-time property updates through Inmovilla API
- SEO-optimized for real estate Costa Blanca, Altea real estate, Alicante property for sale
- Mobile-friendly with excellent Core Web Vitals
- Fully editable through Sanity CMS
This project proves that even with a CRM like Inmovilla, it’s possible to build a high-performance, modern and distinctive real-estate platform — when design and development truly work together.
