Inclusive design provides a framework for making decisions that support the health, safety, productivity, enjoyment, and autonomy of a site and building's occupants. When designing sites, several factors contribute to the usability and functioning of the project, such as sensitivity to the social context, sympathy with the local ecology and natural environment, continuity of circulation and movement, and acuity regarding material selection. Grading, or the manipulation of topography and landscapes, is a core task of site design, particularly for open-site buildings and complexes. The aims are twofold: to effectively manage storm water and other surface waters and to design meaningful building-landscape relationships. Design must consider the continuum from site access to building entry, and all transitions that occur along the way. The design of wayfinding systems need to include: identifying and marking spaces, grouping spaces, and linking and organizing spaces through both architectural and graphic means.
