A Boutique Builder with Big Vision

ONE Residential Builders is a boutique residential construction firm founded by Gary Fuller, an architect by training, a builder by passion, and a businessperson by experience. We specialize in high-end custom homes and major remodels throughout the Denver metro area.

What makes us different? It’s simple: focus. We only take on two projects at a time, which means no rushed timelines, no overstretched teams, and no surprises. Instead, you get a builder who is there—on site, every day—leading the charge and making sure every detail aligns with your vision.

Gary’s path to building is anything but typical. After a successful career in corporate America, he made the leap into premium home construction and never looked back. He combines the structure and clarity of a business executive with the creativity and hands-on experience of an architect and craftsman. And he surrounds himself with people who share those values and skills.

Our Core Values:

  • Quality over quantity
  • Transparent, respectful communication
  • Thoughtful design and execution
  • Long-term relationships—not one-time transactions

We’ve built homes for well-known figures, industry leaders, and families who want a trusted partner to walk with them through one of life’s biggest investments.

If you’re looking for a team that’s as invested in your home as you are, we’d love to meet you.
