The book explores, from an interior design point of view, the dichotomy of home vs. house in the terms of occupation vs. adaptation, the dialogue which is established between the needs of the inhabitants and the answers given by the space itself, through adaptations and variations of the interiors, in order to welcome and foster the expression of the occupants' identities. The concept of "interior legacy" will describe what interior spaces leave us with after their use, in terms of materials and remains, but also of memories.?The role of the interior designer is to foresee these evolutions and arrange the house as a container, so that it can best accommodate transformations and, in particular for temporary houses, the different identities of its inhabitants. This means knowing how to design adaptations over the course of time, managing the necessary changes so as to implement the design in its entirety, in its complete temporality: past, present and, most importantly, future. This idea of designing the future transformations of the spaces and at the same time leaving a trace, a signal of the past uses, can be called the legacies of the interiors with the intention of leaving something to the future, to the next generations. Research Fellow at the Design Department and Adjunct Professor in Interior and Service Design at the School of Design of the Politecnico di Milano. She is Visiting Professor in several international schools of design.?Her most recent Design for Social Innovation research projects are: "campUS" (2014-16), a local research project which has been awarded the XXV Compasso d'Oro (2018), "Human Cities ? Challenging the City Scale" (2014-18) and "Comunicare Ospitando" (2017-now) a research project for the Polimi residences. Her PhD research was about "temporary living", especially in the contest of mega-events. She designed the interiors and services for the Expo Village for Expo Milan 2015 and she founded "MyHoming" (2013) with Angela Ponzini.
