¡Qué onda! Nice to meet you.

The Gold Coast Group was founded by Ronny Marty, a competitive cyclist and Zurich native who fell in love with Baja California Sur over 20 years ago.

Growing up in Switzerland, precision wasn't just a habit—it was a way of life. When Ronny relocated to the sun-drenched coast of El Pescadero, he noticed something missing in the local construction scene: the seamless marriage of uncompromising Swiss quality and authentic coastal indoor-outdoor architecture .

Today, our workshop and headquarters call Pescadero home, but our projects span across Cabo San Lucas, Cerritos, and the entire B.C.S. corridor.

We don't believe in cutting corners or leaving clients in the dark. Whether we’re crafting a contemporary cliffside villa in Cabo, designing a boutique commercial hideaway, or managing your coastal estate, we bring clockwork reliability, clear communication, and artisanal care to every single square foot. We also believe in using the latest building techniques to create efficient and sustainable homes via corefoammx.com insulation.

We believe building in Baja should feel like an adventure, not a headache.
