The following article presents "Rethinking the boulevard", an intervention initiative as a vertical garden built in a collaborative way between residents of the neighbourhood, students of the Master's Degree in Artistic Education in Social and Cultural Institutions of the Complutense University of Madrid, and professionals from the Municipal Centre for Community Health (CMSc) of Puente de Vallecas, for the main facade of this centre. The objective is to turn the space adjacent to the CMSc, which is characterized by its diverse problems (cleanliness, problems of coexistence, stigmatization, etc.) into a healthy meeting point through care and participation. This intervention has been developed in different phases (from November 2017 to June 2018) in which a promoting group is formed that together with the community is building and rethinking this space through activities carried out in community events. In this way, we have resorted to collaborative art methodologies to design a creative proposal that would allow us to achieve an objective related to health promotion. It can be concluded that the maintenance of the garden through the care of neighbors and professionals of the CMSc, shows that this type of initiative can be useful to involve the community in the creation and rethinking of spaces in healthier places.
