The relationship between human behaviour and urban form is a difficult phenomenon to study, as well as interesting. The same is for the relationship between child development and public space.

The aim of this proposal is to begin a wide reflexion about the architectural quality of public spaces and its impact in children and society development. The main goal is to design a methodological strategy that allows the public space diagnosis from a lot of knowledge areas. Through own architectural knowledge, we wish to make a process able to determine the social, physical and symbolic quality of any space.

This diagnosis will be made through perception. It is more interesting to study the complete spatial experience because it includes all senses and all times. It becomes an active cognitive process, where forms, smells, textures and noises become memory, knowledge, thinking, identity, etc.

In this way, this research always shows architecture as an interactive phenomenon between people and the built environment (Lynch 1960, Jacobs 1961). An interaction that takes places almost in three spaces: mental, physical and social spaces. So that, is very important to consider this spaces according to “creative chronotope” (Muntañola 2008). Any built form should be evaluated about three aspects: design, construction and use.

We will analyse the urban reality through the children point of view, because child development and public space are very closely related (Jacobs 1961, Piaget 1976, Moore 1978, Tonucci 2005). Because of this, programs such as “Child Friendly Cities” of UNICEF made the Urban Quality Indicators, which are being used in many places around the world.

Obviously, you can understand that it must necessarily be an interdisciplinary research work, where the architecture is central and essential, but neither the first nor the most important.

Also, there are a lot of things that make this approach research original. In first place, we will use new software tools to measure the human behaviour and interactions in public space, and the spatial syntax (Hillier 2004). In second place, we will use the citizen participation. Indirectly, we will observe the paths and actions of persons in public space, and directly, we will asked to them about the quality of public space. In third place, we try to build a Child Friendly City in the metropolitan area of Barcelona. The city of Cerdanyola will be a good socio-physical context to test this method.

Speaking about methodology for data collection, we will use several techniques through several scales: territorial, urban and architectural. Each scale will have a different approach and it will have different study objects.

Finally, with this work we want to continue a lot of studies about public space as a multi-spatial phenomenon.
