A Reputation for Excellence: One Build at a Time


The building process is methodical. It shouldn’t be rushed. There’s an order that ensures a quality outcome. Craftsmanship takes time and patience. Each step builds on the next to create a more finished product. Custom On-Site Builders, Inc. understands the importance of the process and how it leads to amazing results. That’s how the company has approached building its stellar reputation, one home at a time.


For over 25 years, Custom On-Site Builders has provided Northern Colorado with the highest level of craftsmanship and homeowner satisfaction. The company creates distinct custom homes in the unique Rocky Mountain tradition. The company prides itself on affordable luxury. They make the process seamless: pick the lot, house model and floorplan. It's also a one-time closing, so homebuyers don’t need to close separately on the lot and home.

Custom On-Site Builders is devoted to building dream homes for Coloradans. The company’s innovative designs ensure homes have a timeless sense of beauty while maximizing the latest energy-efficient materials and designs. Every home is built with the highest standards of energy efficiency. These homes are better for the environment, reduce monthly costs and boost long-term home value.


The team works closely with homebuyers to build personalized spaces that reflect their vision and Custom On-Sites commitment to excellence. Whether they choose to build on their lot or one of the company’s, each home is designed and engineered to maximize the space. Buyers can pick from existing floorplans that can then be customized to the family’s uniqueness. They can also work with an architect to create an entirely custom home.

Custom-On Site Builders has built homes across Northern Colorado. They’re currently one of only several select custom builders who are building in the master-planned community of Heron Lakes in Berthoud. This subdivision has it all: water, mountain views and custom-built homes. The community also boasts one of the only TPC golf courses in the country – and the only one in Colorado.
