Our Commitment

To build every new home or custom addition and remodel with honesty using our 35 years of experience. This commitment to excellence ensures our homeowners their new home is of enduring quality and timeless design.

Tim Lyons, principal of Colorado By Design, has made a conscious decision to remain a small custom builder. This hands on approach enables him to repond quickly during the building process. It allows him to maintain his vision of designing and building truly personalized custom homes. Tim combines personal attention with integrity, creativity, craftsmanship and accountability to create unique personal sanctuaries.

From the beginning sustainability and innovation have been part of the foundation of our custom building process. We have always looked for new products and building techniques that protect our environment as well as making good economic sense. These new products and building techniques are thoroughly researched. Those products and techniques that add value and protect our environment are then incorporated into our new homes.

Communication is a hallmark of our custom building projects. It is one of the reasons our custom projects are so successful. We take pride in developing partnerships with our homeowners. We ask questions and listen to the answers. We will examine both the what of the project as well as the why.

Our sub-contractors and suppliers are a vital element to our vision. They are a tremendous resource to all our projects. Many of these fine associates have been with us for years and we value their contributions.

Our goal is to make your custom building process a creative and fulfilling experience.


Tim Lyons, principal of Colorado By Design, was inspired to be a custom builder while working as an apprentice for a small custom builder in Southern Ohio. What started as a way to pay for a college education turned into a life long passion.

By seeking challenges and responsibilities Tim moved from his entry level position to working in the many facets of the custom building process. Through hands on experience and study Tim gained a greater understanding of the many stages of residential building.

The understanding of the fundamentals and nuances of residential building has helped Tim weave the practical aspects of custom building with the aesthetics, visions, and dreams of the homeowners with whom he works with.

For over 35 years Tim has proved that honesty, innovation and a commitment to enduring quality is the right way to custom build.
