Research, by and in the various disciplines of design, has a very young life in relation to other disciplines and; to this contribute the doctorates that train researchers, who attend to the phenomena that occur with the products of the disciplines of design and, in this case, the research from those who conceive and materialize the products, with ideas of building an area of knowledge. Here some doctoral texts are presented, in order to account for the phenomena that involve the built spaces that are inhabited in all their scales and of the utilitarian, artistic and graphic communication objects, which help to define and qualify these spaces to constitute integrated, the human habitat. Likewise, for the study of spaces and objects, their material nature has been considered. intangible or virtual; its historical-cultural dimension and, although obvious, the relationship between spaces and objects, and with people and the natural environment.
