Established in 2003 by Mehdi Momen, Concept Design Group is one of Southern California’s premier Design-Build firms.

With deep roots in both Design and construction management, we specialize in creating inspiring spaces residential and commercial that reflect the unique vision and lifestyle of each client.

From modern minimalism to classic elegance, our diverse portfolio highlights our commitment to exceptional craftsmanship, innovative design, and functional beauty.

We’ve successfully designed and built projects across Northern and Southern California, always with attention to detail, efficiency, and quality.

Our dedicated team ensures every phase from concept to completion is guided by thoughtful planning, budget-conscious solutions, and a deep respect for timelines. At Concept Design Group, we don’t just build structures we build trust, creativity, and lasting value.

Our design-build approach offers a seamless experience by integrating both design and construction under one roof.

This collaborative method eliminates the gap between architect and builder, delivering efficient, high-quality outcomes tailored to your vision.
