About us

Silverthorne Homebuilders was founded by Jim Work in 2010 as a response to the need for quality construction and honest builders in Sycamore and surrounding areas. Our owner & some of our team reside with their families in a Silverthorne Custom home in communities we build in, and are actively involved in the day-to-day production of the company to ensure the highest quality is delivered to each new homeowner. A commitment to customer-first relationships, quality building, and an efficient process has helped make Silverthorne one of the most established locally owned and operated builders.

Two-story new construction homeOver the years, the company has grown through word-of-mouth referrals from existing homeowners, and has expanded into multiple communities outside of Sycamore, including Genoa, Rockton, Maple Park, Hampshire, Burlington and as far west as Iowa servicing the entire Quad Cities region. All Silverthorne homes are customizable as a commitment to our customer-first nature. So whether you want to increase the size of a room, or build your house around your piano, Silverthorne will work with you to make your dream home come to life.

Our Core Values


We value relationships with our customers, the communities in which we build, and all who work for and with us throughout the building process. We believe in a customer-first mentality, which allows us to deliver quality homes and help build a great community for our homeowners to live. Over 70% of our business is from current homeowner referrals, you might even be here because of a customer referral!

We are committed to using local businesses first, resulting in an attention to the quality of construction from those building in their own community. It’s likely you will meet these folks throughout the building process, and see how they share the same commitment to integrity, relationships, and performance as the entire Silverthorne team.


Silverthorne has been committed to the community since the beginning; while many builders walked away from the area during a challenging economy,  Jim saw the need for the community to keep growing. One by one, he continued to build homes within the area to ensure the homeowners moving to the community received a quality home, and the community didn’t suffer as a result of something out of their control.


On the job site or in the office, we value efficient construction schedules and responsible purchasing, putting the customer’s needs first and maintaining a commitment to the personalization of a new home. Whether you’re moving out of your current residence by a certain date, or keeping construction financing costs to a minimum, our commitment to performance and efficiency will benefit you.
