The present inquiring subject is related with the study of two residences of small scale of the Japanese architect Tadao Ando. It is the 4x4 house and Row house Sumiyoshi, extensive report for what is held inside the copy that is accompanied with photographic material. The method of recording and analysis constitutes also the core of work. It has to do with the diagrammatic representations (diagrams). With this process, I place as my fundamental objective electing all these well hidden information that does not become immediately perceptible and bring in the surface elements for the intentions of architect and useful conclusions on the strategy of planning at the all duration of the final composition.

 One of the criteria of choice of the particular residences constituted the fact that they belong in the space of small manufactures with the attribute that they have they provide the permanent human living. Is it feasible therefore for somebody to live or to live together with others in a  such house without all the comforts and spaciousness of conventional model of living? The second criterion of choice was the fact that Ando is characterized for the social extensions that acquire his architecture placing the human factor into space particularly important, while the basic element of his compositions, constitute the heavy and bulky structural systems that he uses. This make renders his energy to work in the level of micro constructions still difficult, requiring particular handlings of volumes and his forms. In the same unit are reported also the characteristic traits that dominate and coexist in the all buildings of architect and become perceptible and in the studied residences.

 The methodology that is followed and concerns in the planning of diagrams, constitutes one from the more important parameters of approach of all inquiring subject. In this part there are recorded the three basic parts that compose it, the technique, the categorisation of produced diagrams and the deposit of personal experience that I acquired from this process. The first unit is completed with the effort of comprehension of term of word <<[diagramma]>> realising and analyzing two categories: the scientific and abstractive diagram.

 The second unit it is about  the presentation of the two residences and the total number  of the diagrams that I have drawn. From the first there are described the two houses and after this part there are presented with photographs and existing drawings while afterwards the completion of this phases, there are presented the 28 diagrammatic representations accompanied from their explanation in the next department of unit.

 Finally, in the conclusion, there are recorded the conclusions that result from the study that constitutes asked this attempt of recording through this method.
