This is the first book to address the design needs of older people and the disabled in the general outdoor built environment. It provides information on design principles essential to urban designers, planners and landscape architects who want to provide for all users of urban space and who wish to achieve true sustainability in their designs. Part one examines the changing experiences of people in the outdoor environment as they age and discusses existing outdoor environments and the aspects and features that help or hinder older people from using and enjoying the outdoor environment. Part two presents the six design principles for streets for life and their many individual components. Using annotated site plans, photographs and line drawings, a range of design features are presented at all scales of the outdoor environment from street layouts and building form to signs and detail. Part three expands on the concept of streets for life as the ultimate goal of inclusive urban design. These are outdoor environments that people are able to confidently understand, navigate and use, regardless of age or circumstance and represent truly sustainable inclusive communities.
