The present research studies in which degree the dwelling and decoration work as a language capable of being understood by subjects of the same culture. The basis of the study is that the homeowner's identity may be inferred by strangers that see different rooms of their house. The subjects were 203 students were distributed in four groups. Each group saw 12 slides of four different rooms: - living room, bathroom, kitchen and bedroom- of each home, randomly ordered. These rooms were chosen because they are the most common rooms in Spanish homes. This means that each group saw three different houses. The total number of houses were four and each home was seen by three groups. The questionnaire used to assess Identity consisted of 24 personality traits listed in 7-point bipolar scale format in which they tried to define the personality of the dweller of the home. The same questionnaire was performed by the owners of the four houses studied. The socioeconomic level was controlled in the way that the subjects and the dwellers were on the same level. The results point to a certain agreement between the observers and the dwellers about the homeowner's identity so that the different rooms facilitate the equal attribution of certain dimensions of identity between the observers and the owners.
