The floor plan is strongly elongated and the entrance is positioned at the south-east corner. Three windows located at the two narrow sides of the initial shape of the plan bring light and ventilation to the interior, leaving, though, the central part of the apartment in darkness. Due to the fact that the two main session rooms and the children area should be placed close to the luminous facades, the architectural intervention emphasized in resolving the most ‘inhospitable’ and dark part of the apartment by arranging the distribution of the circulation leading from the entrance to the two main session rooms. The proposal places a luminous cylindrical void right at the ‘heart’ of the space. The circular shape reintroduces the element of light in the darkest part of the apartment while rearranges the structure of the floor plan. This reference point reverses the outward mood of the former space establishing a new balance between the center and the periphery. The bright circular shape/the center of light, a symbol of self-knowledge, becomes an antechamber and a temporary waiting area before entering the two rooms of psychotherapy. The path leading to it, becomes a path of initiation leading to the interior, the space of the self, a space of eminently in habitation.
