At the beginning of the twenty first century, the focus from municipal management on open public spaces acquired special relevance as a way of integrating marginal neighborhoods. Metropolitan parks are a successful urban intervention due to their large span and massive turnout. However, restricted or close access characteristics generate more limits in their use and more physical and visual borders. As a counterbalance, one could ask: How do the physical and social components of the neighborhood scale contribute to an IPS design with functions and spaces for their neighbors? This paper discusses bibliography pertinent to this question and the last information and statistical analysis of housing and population census. The quantitative and qualitative analysis is accomplished by comparing metropolitan and neighborhood scales with the IPS strategic procedure experienced from conception to functioning. As a case study, the two most representative space scales are taken from Metropolitan Lima's Carabayllo District. Main results: The three components are valued: neighborhood, strategic process, and urban-architectural projects. Neighborhood influences citizen´s behaviors and allows defining the IPS as a social space marker and an extension of home, in good habitability and security conditions. Strategic process defines the reinforcement of neighborhood actors' capacities for their active participation in obtaining the IPS. Urban-architectural projects, whose conception and design as a daily use allows their insertion in the physical and social fabric, eliminating borders and existing limitations. The result shows that the strategic procedure permits generating the positive effects sought on the IPS, as opposed to the metropolitan scale, which only satisfies needs inside public space. The challenge is to replicate the positive aspects of the proposed strategic procedure and reorient public investment towards more IPS.
