Welcome to James Madson Design. We are a building design studio in San Francisco specializing in residential remodels, additions, and new custom homes. We have completed projects in over twenty municipalities of Northern California, covering the Bay Area, Central Valley, and the Sierra foothills. In projects ranging from a “19th century” farmhouse to a minimalist contemporary home, our credo is to embrace all aesthetics as reflections of a common goal: a home that brings both comfort and interest to your daily life.
