About Us

Karl Holtermann Designer + Builder LLC provides the the complete architectural design and construction services to residential clients who choose to do a variety of projects. Many of my clients are busy professional with a high expectations. I exceed expectations. "I work closely with clients to achieve the design you always wanted but never could have come up with on your own". My 20 years of experience working closely with craftsmen and craftswomen of the highest caliber allows me to do virtually any type of remodel or addition. As the Designer and Builder nothing is lost in the translation from imagination to reality. I am the only person you need to meet with. It's my job to coordinate, schedule and manage subcontractors so we all have a clear future. Many clients choosing to remodel have heard or experienced horror stories. It is my job to make this a positive experience, and an enjoyable process you will fondly recall for years. Proudly, many of my clients are repeat customers. The scope and budget of my projects varies greatly based on the needs and goals of clients. It is my job to listen to your goals, needs and objectives to provide for you the ideal solution (s) so you are able to make decisions.
