This study encouraged by the Catalan Ombudsman about the evaluation of the Public Play areas, with the idea to promote the need to activate the promulgation of the law, it has permitted us to elaborate a tool who brings reflection elements about the quality of the play areas in a general sense and also it has permitted us to make a pattern to evaluate the different aspects who make up this space as whole. The study also has made possible, to create a CDRom as an interactive tool, in order to be used by town planners, architects, designers, local communities etc, as far it is concerned to the social-physical context of the urban situation, as far it is concerned to any other described characteristics of the play areas.
