*3.1.1 Planning*

In **Figures 3–6**, using the futures triangle tool, it can be seen how actions from the past emerge are linked to milestones in the present and future projections are generated. Both actions and milestones respond to bibliographical evidence researched from secondary sources, while future projection uses audio-visual information such as series, documentaries or films that allow a general visualisation of probable futures.

In this first stage, it is fundamental to lay the theoretical foundations with scientific evidence of past and present events analysed through the bibliographical review of more than one hundred secondary sources including scientific articles, press releases and books, using the technique of critical content analysis, which allowed us to articulate possible future scenarios created through audio-visual sources such as films, documentaries or series, analysing more than sixty case studies of houses or residences created in hypothetical futures. It can be observed that the triangles that present the most evidence are those of chaos and evolution, while GAIA and progress present less evidence, which allows us to establish a first tendency that will be defined in the following stages.

It is also important to note that in the triangles of futures it is observed that there are gaps in the line of the present, which psychologically indicates the level of uncertainty and concern of humanity in the face of events that cannot be predicted. In this sense, the future of progress is the most favourable and feasible for humans, while the chaotic future is the least desirable
