Expert Home Additions in Roaring Fork Valley, CO

A home addition is one of the most direct ways to gain living space without leaving the Roaring Fork Valley property you already own. Whether you need a primary suite, a guest wing, a garage with living space above, or a larger main living area, Pegasus Custom Homes plans and builds additions that connect cleanly to your existing structure. Our work draws on over 35 years of building experience across Europe and the United States, including more than two decades building in the US. That background shapes how we approach every addition: with careful attention to structural integration, material selection suited to mountain conditions, and design that respects the existing home. Roaring Fork Valley properties often sit on sloped terrain, which affects foundation work and access planning for any addition. We account for those site realities from the start. If you are ready to expand your home in Aspen, Basalt, Carbondale, Glenwood Springs, or anywhere across the valley, contact Pegasus Custom Homes to talk through your project.

I couldn’t recommend Pegasus Customs highly enough. They did an excellent job on my home renovation from start to finish, and the quality of their work really speaks for itself. Professional, reliable, hardworking, and clearly take pride in what they do.

We had an exceptional experience building our home with Pegasus Custom Homes. From the very beginning, we felt that we were in incredibly capable and trustworthy hands. Building a home is a huge undertaking, and there are so many details that can easily become overwhelming. What stood out to us most was the level of care, organization, and attention to detail that went into every part of the process. He and his team showed up every single day, were incredibly responsive, and took genuine pride in their work. They didn’t just build our house, they cared about getting it right. Even more impressive, we were able to move in exactly when we were promised. That is remarkable in the world of construction. We could not be happier with the quality of the craftsmanship. More than anything, we appreciated knowing that we were working with a builder who was honest, dependable, and truly invested in creating a home that we would be proud of for years to come. We would recommend Pegasus Custom Homes without hesitation. If you are looking for a builder who takes tremendous pride in what they do and stands behind their work, Pegasus is an exceptional choice.

Exceptional service! The owner always over communicated - we never felt like we were not in the loop with anything. His team was professional soft spoken and confident. The quality they delivered was better than we expected and they were able to execute and close out our project ahead of schedule. We highly recommend the Pegasus team. Thanks so much Koby!!
