Pahlmann's clients' working files contain the most thorough coverage of his interior design projects. The length of the files vary with the level of project complexity and the length of the client's relationship with Pahlmann. A typical file contains rough sketches of the rooms to be decorated, blueprints of the room, Polaroid photos showing the "before" status of the room, notes of meetings, worksheets, cost estimates, correspondence with clients and dealers, and room-by-room suggestions of color schemes with samples of wallpaper, upholstery, tiles, carpet and photographs of all furniture. The bulk of the coverage is from the last two decades of Pahlmann's career.
