• Conner Construction

  4 homes2 communities

  Chris Conner, a lifelong Idahoan, began building homes in the late 1970s with the founding of Chris Conner Construction. Over the course of his career, he established a reputation for quality craftsmanship and integrity throughout the Treasure Valley. In 2016, he passed the torch to his son Clayton, who founded Conner Construction—carrying forward that legacy with a fresh, forward-thinking perspective. Raised on Boise job sites and working in construction since the age of 12, Clayton developed a deep, hands-on understanding of the craft early on. He later earned his Bachelor’s degree in Construction Management, along with a minor in Business, from Boise State University—graduating with honors in just three and a half years. Clayton has built a reputation for excellence in hillside construction, custom homes, and complex residential projects. Known for his attention to detail and commitment to quality, he approaches every build with precision and care. In addition to his work in the field, Clayton has served as both President and Vice President of the Building Contractors Association of Southwestern Idaho, where he has supported the next generation of builders and helped guide first-time buyers toward homeownership. Today, Clayton continues to build on his family’s legacy—making Conner Construction a trusted name in Boise for craftsmanship, creativity, and local commitment.

• Harding Homes

  3 homes1 community

  With roots stretching back four generations, the Harding family has been an integral part of shaping Idaho's landscape. My great-grandfather first came to Salmon River area in the 1880s as an original homesteader before Idaho achieved statehood. The ranch he established remains in our family to this day! My grandfather carried on this legacy by joining Union Pacific’s efforts to develop the United States' first ski resort, Sun Valley. In 1936, he partnered with the Sun Valley Corporation to help build the iconic Sun Valley Lodge and the historic Roundhouse. For over 30 years, our team at Harding Homes has proudly continued this tradition right here in the Treasure Valley, creating homes that reflect the unique spirit of our community. We believe building a home is about creating spaces that enhance daily life and enrich your well-being. Every detail of our work is infused with the same care and precision that has been handed down through generations. From the first design sketch to the final coat of paint, we are dedicated to ensuring your home is built to the highest standards.
