Madrid’s General Plan is being revised, a complex moment in which there is a confrontation (sometimes far from harmonious) between the hopes and interests of all those related to the city. This Biblio is a volume of thoughts about this issue, which reunites the voices, among other, of a set of people I happen to know and appreciate, as I have worked with them. This is especially true for Julio Vinuesa, from which I have learned many things coming from his geographical vision of housing and cities. For those that are in Madrid, this book is linked to an ongoing set of interesting conferences (something I’m sure of, even if most of the time my work prevents my presence).
