The idea of maintaining economic prosperity through planned ob-solescence defined much of the twentieth century. Today, amid es-calating ecological crises, the systematic replacement of outdat-ed objects and infrastructures must be considered unsustainable.

A profound social change can be observed in the areas of mobility, work, and trade, as well as in the practice of faith, especially in cities. As a result, certain building typologies such as petrol stations, offices, shopping centers, cinemas, and churches are being used less, thus becoming increasingly obsolete and contributing to the obsolescence of the city. Transformation strategies are needed instead.

The book 'Rethinking Obsolete Typologies' focuses on spatial obsolescence. As new economic and social dynamics emerge, urban typologies of the modern era such as shopping malls, cinemas, gas stations, and others are becoming ob-solete. These structures demand imaginative forms of reuse. Rath-er than demolition and replacement, this publication advocates for spatial continuity and the creative adaptation of the existing built environment. It explores how architecture can be transformed with a sense of social and ecological responsibility, offering insights into the spatial, structural, and procedural possibilities for transforma-tion in a time of climate urgency and shifting urban needs.

Three strategies must be considered for the efficient transformation of these structures: the conversion of existing architecture and the preservation of the gray energy they embody; the maximization of land use; and the strengthening of ecological functions to improve the urban microclimate and the quality of living space.
