Design concepts for projects are categorized under which type of theory?

Design concepts for projects fall under the category of prescriptive theory. This type of theory provides guidelines, rules, or frameworks that inform how design should be approached and executed. It focuses on establishing norms and standards that architects and designers can follow to achieve certain outcomes in their work.

Prescriptive theory is particularly important in architecture because it offers a structured way to interpret design principles and apply them in practice. For instance, it may dictate certain aspects such as spatial organization, material selection, and sustainability considerations that should be integrated into design concepts to enhance functionality and aesthetics.

Descriptive theory, on the other hand, primarily focuses on describing how things are rather than how they should be. It provides an analysis of existing architectural practices without offering specific guidance for future applications.

Applied theory refers to theoretical constructs that are put into practice, but it often does not encompass the prescriptive nature needed for developing design concepts.

Normative theory, similar to prescriptive theory, sets ideals and benchmarks but tends to be more theoretical than practical in the context of project design.

Thus, prescriptive theory is the most appropriate category for design concepts, as it directly relates to guiding the development and implementation of architectural projects.
