Abstract
Design spaces can be read in two complementary structural and compositional dimensions: the implicit dimension, and the formal dimension. This study aimed to answer the following questions: What are the phases of the original idea transformation in the design process? Does taking advantage of the implicit dimension of others' interior spaces count as inspiration or plagiarism? Participants comprised nine postgraduate students, who were asked to copy others' project ideas by applying four design phases: idea source, test, choice, and output. The results showed that plagiarism of the concept of others' work could not occur unless the concept copies the structural, functional, and aesthetic aspects of the design space at the level of its components and the relationships between them. Otherwise, taking advantage of the implicit dimension of others' project ideas can be an inspiration. The results are expected to increase awareness among interior design instructors in higher education.
