Figuring Out the Interiors through the Geometric Tools of Representation: The Illusory Cast of Design

Interior design is taught to be an essential tool for envisioning and modeling the environments we live in. Representing interior spaces through drawings and physical models requires a continuous process of imagination. The chapter exploits the projective tools for illusory design describing the processes of representation to design and build interiors but also their perception as a space. Crucial is the role of perspective in designing and building interiors; techniques of perspective, distancing itself from the mathematical problems, become a projective tool to add illusory qualities and creating the perfect tuning among spaces that remind us that designing methods aim to add dimensions to the human sphere, not only in the physical one but also in the creation of material images and allegories. The research highlights the principles of projective-geometric design of illusory spaces. Descriptive geometry and disciplines of representation provide, in the many phases of design, scientific and artistic tools for practical resolutions of geometric and constructive problems.
