Since the 1960's problems have increased within multifamily residential environments. (Duncan, 1996). Some of these problems include: buildings that are too large, little consideration for the human factor, lack of green areas, lack of natural elements, and lack of play areas for the children. It is essential that we improve these areas for the health, safety, and welfare of residents and find ways to avoid problems in the future. Previous research has shown that when an environment is aesthetically pleasing, an individual will experience higher levels of satisfaction within their environment. (Amérigo and Aragonés, 1997). It is also noted that the presence of greenery within environments can have a positive as well as restorative effect on individuals and that people prefer trees in their environment. (Kaplan and Kaplan, 1989) Additionally, when individuals are provided with their own outdoor garden plot or outdoor area, they will have a much higher attachment to their outdoor environment and their satisfaction will increase if they are provided with sufficient personal space. The goal of this research is to help bridge the gap of opinion between residents and building professionals by providing a tool for creating pleasant, stress free outdoor environments. It has been shown through our research that by using an expert evaluation tool, it is possible to predict certain aspects of the residents' overall attachment to their outdoor environment in multifamily housing areas.
