The name behind the work
K. James Building Co. is named in memory of my father. I’m Keith O’Donnell, owner and carpenter, with a particular love for finish work. My focus is on thoughtful residential improvements and custom interiors—spaces that work well, feel personal, and reward attention to detail.
