It is increasingly well known that the Interior Designer of the XXI century must have a greater number of interior design project tools that help them to function in an increasingly competitive world in terms of discipline, where when they propose to investigate in In-depth, the design treatment of the different residential, commercial, work, tourist, and landscape spaces, can be manifested from a process of acts and decisions of strong creativity. Likewise, it must generate a clear and identifying design concept for the client to which it responds, basing each project decision and providing its proposal with powerful theoretical-conceptual support, in order to achieve the different qualities of spaces that are possible to materialize. Knowing how to provide environments with a particularized character, making the conceptual design as a whole, starting from the personalization of each space, be it for the use it is intended for, is the challenge that will provide the interior designer with an expression of his own, as a differentiating variable in the world of work. In interior design, great things are achieved with a thorough knowledge of the variables that influence the moment of projecting; keeping in mind the other fundamental condiments that are: interest, dedication, and the desire to experiment. The interior space is transformed day by day: the search for new sensory experiences has begun and this requires a redefinition of the intervention in the project.
