Challenging Custom New Build and Remodeling Projects – Boulder Custom Homes at their best!

As an experienced home builder in Boulder, and renovation expert, we enjoy challenging projects, rather than shying away from them. Our unique, organized, approach sets a consistently high standard which sets us apart from other Boulder contractors, general contractors and Boulder builders. Our project facilitation team values internal company communication as it does communication with company clients. The result is a much more streamlined process and a final product that much more closely resembles the client’s initial vision. This is all done with the intention of creating the least impact on the client’s life as possible.  Let one of the premier custom home builders in Colorado take the lead on this important journey – we are experienced at creating Boulder custom homes that stand apart.

There are many Boulder builders from which to choose, but few with the combination of skill, experience and drive provided by the Ellis Construction Team. This team is single-minded in its focus on the successful completion of your architectural dream just as they were in completing in excess of 100 residential Boulder construction remodeling and custom build projects inside Boulder City and County.

Ellis Construction takes a collaborative approach to working with its clients, inviting them to be involved in the construction process. Working closely with the client’s design team, and including the client in the process, is highly correlated with the successful completion of a unique custom home, or remodeling project, that reflects the client’s true vision.  Diligently abiding by this process is what sets Ellis Construction apart from other Boulder builders – and what has led to their being recognized in the top tier of custom home builders in Colorado.  Boulder construction projects tend to be innovative, cutting edge projects which only enhances our enthusiasm as an innovative builder.

Secret to our Success

Over 10+ years in the business Ellis Construction has developed a highly valuable process which is initiated during the design process and continued through the remodeling – new construction phases. Having the entire team under one roof allows for consistent fulfillment and a superior customer experience. This sets a solid groundwork of communication and clarity which inevitably leads toward a smoother process and exceptional results.  This is also what sets Ellis Construction apart from other Boulder builders.  We invite you to consider Ellis as the custom home builder for your next Boulder construction project.
