Our Process Delivers
Quality and Value

Building a custom lake home, for most people, is one of the largest investments of their lives. The Colby Construction process is designed to ensure quality results with exceptional value. Land layout is an important factor in design and budget. Variables such as placement, view, topography and drainage are carefully reviewed and managed. As a custom home builder and one of the premier Lake Country lake home builders, we strive to create the quality custom lake home you have always wanted. Our hands-on and team-oriented process is dedicated to exceeding expectations for quality and customer satisfaction to give you the home of your dreams.

Our Process

“Our experience with Colby Construction was outstanding from the design, to the plans and throughout the entire construction process. After two years in our custom home, we continue to be impressed with the overall quality of the construction and all of the thoughtful details. The entire Colby team was exceptionally knowledgeable, reliable and professional and it was a pleasure to have them as our partner throughout the entire design build process. A truly outstanding experience.”
