Abstract The starting point of this research is the assumption that nowadays to regenerate – rather than to build from scratch – is a necessity. Regeneration is fundamental to avoid further land consumption, curb urban sprawl and reduce resources consumption. In the context of urban regeneration, residential periphery deserves special attention. Residential peripheries are nowadays marginal, because they are awfully connected, undifferentiated, monofunctional and lacking in basic services. They are unable to respond to changed housing requirements, and inadequate from morphological, typological and energetic perspectives. At the same time, these neighborhoods are a significant resource, because of their size and transformation potentialities. The chosen approach considers density as the main criterion to guide and check the projects of reconstruction of residential periphery. Density, as an urban variable, is a quantitative parameter that affects both architecture and life quality, i.e., the quality of life of the inhabitants of the architecture. In this research the concept of density is extended to a three-fold meaning: density of buildings (with particular attention to density interpretation in terms of surface: FAR – floor area ratio), density of encounter (whose values are randomness and closeness), and density of uses (differentiation of activities and functions). The choice to focus on Oriol Bohigas, architect that works in Barcelona since 1951, is justified by his vision of planning and also by his determination to promote city reconstruction rather than city expansion. Indeed, he is in favor of a compact city, with a high density of people and activities. The work of Bohigas takes place in the space between plan and project: the plan tends to the project and the vision of the process is always recognizable. From this perspective, the local dimension gains a relevant value and the transformation strategy for the city is improved through punctual actions for services development and reconstruction of public spaces. The elements involved in regeneration are housing, city block and urban space, whose hierarchies and forms are pivotal points for planning. Following this recipe, the urban project becomes a strategy for high impact changes. To compare with criteria and solutions in plans and projects of Oriol Bohigas, a selection of representative projects will be analyzed, through the reading key of density, with focus on residential themes and actions in the consolidated city. The outcomes of this research will include an evaluation of the relevance of cognitive contents that relate the work of Bohigas with the concept of density. Also included will be the extrapolation by deduction of a possible “Bohigas Method”, an intervention method, defined by project and process strategies, for the regeneration of urban periphery. These strategies are based on concepts like: functional differentiation, strong relation between plan and project, local dimension, city block as regulation element and urban space differentiation, through hierarchies and forms.
