The lack of compliance of the built environment and of the products, with needs that can be very different causes a state of handicap. The lack of ability is a handicap only if the project has not taken it into account. After more than 40 years of regulations on the elimination of architectural barriers, the accessibility of places and objects by people with disabilities is nowadays a minimum requirement. Design for All or “Planning for All” goes beyond, is innovative, is a shared, transversal and multidisciplinary approach to design, that can be applied to communication systems, places, public services and fast-moving consumer goods, so that these can be used by the biggest possible number of people. What are the problems, the methodologies, the working tools and the criteria to take into account when planning or evaluating a design for All planning? What are the suitable audit tools? This publication seeks to highlight the different fields of application, through different professional and research experiences. The first volume examines some of the main research fields and some examples at urban level; the second one collects some demonstrations related to architectural, product and services design, as well as to the topical theme of university training. We are talking about a person-centred planning, more than planning for categories of people, that takes into account needs and expectations, also unexpressed ones. A Design which satisfies Everybody: does it really exist, can it be implemented in the real world? If it is useful – as it seems – that this approach should be an aim, with this publication we want to urge a debate and a deeper study, for a more and more widespread application of Design for All in all professional and research fields.
