The Dementia-Friendly Neighbourhood Design Guide serves as a valuable resource for the replication and expansion of dementia-friendly neighbourhoods island-wide. This Guide, built upon the foundation of the AIC-CLC Dementia-Friendly Neighbourhood Study, consolidates and harmonises relevant dementia-friendly principles, guidelines, tools, and perspectives from our various government agencies and international experts. This is a design resource that offers guidance to built environment professionals on design considerations and strategies to creating Dementia-Friendly Neighbourhoods in Singapore’s high-rise, high-density context.
