Boulder & Nederland's premier residential & commercial builders

Our Philosophy

At The Magnolia Building Company, we believe that when it comes to construction, it’s all about client satisfaction. Building a new custom home or remodeling an existing home is a major life experience that takes a lot of time and energy. As a Boulder & Nederland general contractor with more than 40 years of combined experience, we believe that this process should be an enjoyable and rewarding one. You should be excited every time you arrive at the job site and see your dream coming together. Simply put, our goal is to be the company we would want to hire – honest, dependable and skilled. Our builders have the expertise, equipment, and resources to get your job done correctly the first time – and most importantly, in a time-efficient manner.
