About Us

Green Valley Custom Builders is a local, family-owned luxury home builder proudly serving Northern Virginia since 2013. We are passionate about transparency, honesty, and craftsmanship, aiming to build more than just homes—we build lifestyles.

A home is a form of self-expression, reflecting your personality, values, and tastes. Our homes feature transitional to modern designs with open floor plans, high ceilings, and expansive windows, seamlessly blending indoor and outdoor spaces. We prioritize cost-efficiency without compromising on luxury or integrity.

Founder and CEO Raj Tamang, PE, LEED AP, a structural engineer with over 20 years of experience, personally reviews every home, ensuring both aesthetic beauty and structural integrity. We focus on long-term performance, addressing key issues like preventing floor sagging, squeaks, and bounce.

Our in-house design and construction teams work together, driving innovation and delivering the highest level of craftsmanship. We offer a robust home warranty program and provide homeowners with an online platform for post-construction support, featuring real-time updates, access to home manuals, and seamless communication with our support team, ensuring continued service and fostering lasting relationships with our clients.

At Green Valley, we redefine luxury living, creating beautiful, sustainable homes that inspire families and elevate lifestyles. Our commitment extends beyond construction; we build lasting relationships with clients, ensuring their needs are met long after they move in.

We craft exceptional homes that exceed industry standards, with a focus on transparency, quality, and sustainability. Our homes are designed to inspire, creating safe, beautiful environments that elevate family life, reflecting our belief that a home is more than just a place to live—it’s an expression of who you are.
