The quality of the built environment has a strong influence on the quality of people’s lives. Buildings and spaces that are designed inclusively, contribute to breaking down barriers. They can greatly enhance a person’s mobility, their sense of belonging and security, their health and well-being. They contribute also to the strengthening of communities whilst responding to the needs of people of all ages and abilities. The challenge for architect’s to-day is to ensure that the built environment will facilitate the active participation and independence of all. This presentation will show how the international case studies meet the concept of universal design and inclusion within the genre of existing and historic buildings. Examples will include: Malahide Parish Centre; Diposit del Marti Spain; St. Mel’s Cathedral Ireland; Viva Blue House Hong Kong; Residential center for people with physical functional diversity Vigatans, Spain. The international presentations gives perspective the varying opportunities that different regions have to implement inclusive design practices.
