    Rooted in the LC Valley, Building for the Future

    Collom Construction calls the Lewis-Clark Valley home—a place known for its strong community and timeless traditions. We honor that heritage while introducing a new approach to building: homes and ADUs designed for efficiency, sustainability, and long-term value.

    Our projects combine local craftsmanship with modern innovation, solar-ready designs, healthy materials, and energy-conscious systems, so you can enjoy the beauty of the Valley without compromising on comfort or responsibility.

Our Foundation: PILLAR Values

At Collom Construction, every project is guided by principles that go beyond building homes—we create spaces that maximize efficiency, honor sustainability, and deliver lasting value. Our PILLAR values define who we are and how we build: Purpose, Innovation, Leadership, Longevity, Affordability, and Responsibility.

Every build solves a real need—whether it’s adding space with an ADU, lowering energy costs, or creating a healthier home environment.
