Objective It is important for interior design practitioners and students to have systematic methods developed to critique interiors. Further, it is important to critique significant spaces, defined here as those that are designed by interior designers and are used by large numbers of people. Research Design A framework for the systematic criticism of retail spaces was developed and used in analysis of the Robinsons–May department store in Glendale, California. Concept and function are the two components of retail store design that were used to form the basis of the criticism framework. This framework guides the critique of the space, sets parameters for analysis, and allows for replication. Analysis Six categories were identified as essential to design concept and function: (a) access from the exterior, (b) the space plan, (c) department identity, jd) visual merchandising, je) fixturing, and (fj codes. These categories are discussed as they relate to concept and function. Key Findings At the Robinsons–May store design concept is supported by the use of form and color as dominant elements within a stylized classical design concept in the space overall, although they are not entirely consistent throughout departments and across all floors. Some unique applications of marketing strategies in department identity, visual merchandising, and fixturing also support the concept. Functionally, the circulation patterns and adjacencies are well conceived; however, there is an absence of adequate accent lighting throughout the space. Conclusion The framework supported the critique of the retail space. Other components could be added to a general framework such as this one that focused on design concept and function. The critique of spaces used by large numbers of people (such as retail department stores) and designed by interior design firms is an important contribution to interior design education and practice.
