Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Timothy D. Keane / This thesis documents an exploratory design process that examines the efficacy of a framework for designing dementia gardens based on: theory, Stephen and Rachel Kaplan’s Attention Restoration Theory (A.R.T.), (Kaplan and Kaplan, 1989) and Roger Ulrich’s Theory of Supportive Gardens (Ulrich, 1999); John Zeisel’s (2007) process for designing dementia gardens; and design details, Claire Cooper Marcus’ Garden Audit Tool (2007) and Moore’s analysis of exemplary dementia gardens (2007). It documents the integration of theory that is not specific to dementia gardens (Kaplans’ A.R.T. and Ulrich’s Theory of Supportive Gardens) with process (Zeisel) and programming elements that are specific to dementia gardens (Cooper Marcus’ Garden Audit Tool Kit and Moore’s exemplary dementia gardens). The framework was developed during an illustrative courtyard design project for a retirement center whose clientele included patients with varying need levels. Throughout the illustrative design project, knowledge of the four A.R.T. characteristics (Being Away, Fascination; Compatibility and Extent) guided design decision-making in an effort to create an engaging environment, where improved health outcomes and restorative person-environment interactions could occur.
