Architecture, of any kind, always shares a constant: it responds to growth. A growth, in population, in production (and therefore consumption), in economy, in culture, in faith and wealth, et cetera. Inevitably, architecture is the result of the need to house more interactions between an ever-growing number of human beings. In a time when we slowly realize that exponential growth can only lead to a global disaster, what should architecture become? Is there still sense in it, knowing that it becomes morally reprehensible to design new buildings? The project confronts the question of a moratorium on new architecture and explores how, through micro-densification, our generation of modifiers can invest the existing in a qualitative way thanks to a thickening of the psychic and physical borders between users; in order to develop spaces that gain in depth without extending in surface. The project invests the cracks and abandoned volumes of a block where several protagonists with disjointed histories, from different times and intentions, meet. It takes on the role of a constructed narrative that finally links a forgotten cinema, a zany church, surviving bourgeois, a modernist tower, and a solitary park, against the backdrop of Lausanne's typical topography.
