This course provides lecture, lab and studio components focused on the integrated relationship between architecture and interior space. The course conceives interior space as the study of light, color, texture and volume as it relates to human scale. The course objectives and outcomes are organized into four phases; gathering, finding, transforming and synthesis - and includes studies on building program, daylight and the haptic study of material. The course builds on the concepts of landscape and site from the ID1 course and prepares students to embrace concepts of tectonics to be considered in ID3. The studio component emphasizes integrated architectural composition; the lab emphasizes exploration and experimentation with design media and other specific design inquiries in support of the studio.
