Between the first sketch and the finished building, or between the first draft and the final text, architecture rests on a dense meshwork of complicities, an intimate scaffolding that histories have often disregarded.

Architects have always created or borrowed practical, conceptual, and discursive means to imagine, communicate, and achieve their work. Such means are neither neutral, nor are they mere technicalities. From the draftsman's pencil and the ephemeral logic of formwork to the complex algorithms of artificial intelligence, the history of instruments is not simply one of technological progress, but of narratives intertwined with architectural theory, and of conceptual and procedural tools structuring design thinking.

Industrial heritage probably reflects the most coherent discourse of continuity between past, present, and future. Industrial sites also encapsulate dichotomic connotations, from places of the avant-garde to derelict spaces, from strong images of empowerment, emancipation, and even propaganda to areas of decay, of marginalized societies. However, as they once were triggers of modernization, industrial sites can be today powerful vectors of change, real engines for social and economic community regeneration.
