1. The first step in interior design projects is to create a digital floor plan and sketch it by hand to allow for quick changes and client feedback. 2. Next, the existing conditions of the room are drawn, including walls, windows, doors, and other features to create a baseline. 3. Potential furniture layouts are then sketched on tracing paper over the existing conditions plan to design the space and select the best layout. Lighting options like direct, indirect, and ambient are also considered.
