'About buildings & food' –– taken the title from 1978 Talking Heads’ record –– take care of the domestic space and the public space from the perspective of food. From this perspective, the relationship between both realities is clarified, since the food traces countless links between these two scenarios: from the supply to the waste, and even when the food separates them, or when we eat on the street we do not do it at home, also allows us to observe new relationships between both spaces. The issue brings together a series of articles that address different issues about food, architecture and the city. Barcelona is present in several of these, but also a collection of cases and things, which we believe is universal. The focus is on the food and the actions that this triggers, especially in the public space, affecting its configuration, but also what it has of everyday theater, with new rhythms and gestures that flood the urban scene at certain times. At the same time, it seems opportune to also pick up on what affects the house at present, with the increasing presence of the prepared food that is delivered at home. In this case the reflection focuses on the dining space and its position in the house, which augurs that this space becomes a central space in the house and opens new perspectives that overcome functionalism.
