The entrance of the public building is a part of an integrated whole that directs the visitors to its use. It has the character of a threshold, but mainly of an extended space, due to the process of approaching and the stages of transition. This is an expression of quality and of communication between the building and the public space.
The archetypes and typologies that an entrance follows in its design may attribute the visual part of its structure. However, the body as a factor of movement is the one that constitutes the tactile dimension of entering and this would fulfill its semiotic interpretation. So, this gives sense to the transition, the path, the process, which determines the spatial organization of the entrance in the social space.
Within this infrastructure of entrance’s space, the tactile part is revealed through the materials that are an index of their quality and their reference to the objects. Besides, architecture is a result of experience and must be comprehended as such.
In the terms of a subjective perception, entrance is a sign of transition from public to private and from external to internal, as though it has a social meaning, reinforced by its use. Nevertheless, symbolism is entailed in the meaning of objects, which is understood through experience; the latter is either an absolute visual one or it is spaced out in the senses as well.
