Concept, for designers, becomes the force and identity behind the progress of a project, and it is consistently referred throughout every stage of its development. At the planning stage of design processes, the first conceptual level of organisation has been applied that the process of form development draws upon the way of thinking which brings meaning to the design (Reid, 2007). Consequently, architects or designers become mediators to translate ideas into designed products. Therefore, to design and preserve continuity and identity, one must acknowledge the physical and social environment and space as an existential experience for people with dementia.
