The interior is situated in a shopping mall. The design initially had to deal with the restrictions in the existing structure: a space broken in two poorly connected separate parts, opposing in character (one’s ceiling too high – the other’s too low, one structured in concrete – the other in steel, one with no natural light – the other overlooking a square with three glass walls, one grid at an angle to the other). Spatial limitations thus initiated the design concept, in which two spaces were treated opposedly: the first as a closed double-height box, and the other as an exposed shallow open space.
The other conceptual references are concerned with function - the care of the hair and the occasional art exhibiting. Both of these activities are intimate, yet performing. One has to isolate oneself, while being exposed to the art(isan). But at the same time, the work of art (or a hairdo) has to stand out, has to be seen. The approach is both exhibitionistic and secretive.
The interior can be treated as hair is; let’s not petrify things that would naturally move. The process begins with the name, La Coulisse  (given by the architect), deriving its meaning from the mobility of the elements and their ability to slide down the scene.
The lower, entrance level, is a grey concrete box. It is partly a one-exhibit gallery, with adaptable lighting system, and partly a waiting area. The tall wall of the box is animated by the curly shadows of the suspended wire sculpture. The box contains a flight of light sheet steel stairs with wooden treads and risers, leading to the hairdresser salon at the upper floor. All the colours used are achromatic, in order to enhance the colour of hair.
The hairdressing area has three two-sided work elements, which slide, hung to the rails in the ceiling. Each element is a raw steel structure which supports two polished mirrors and the projecting reflectors, with shelves and the elctrical power provided. The ceiling is suspended on steel ribbon-shaped frames, and made of transparent wire cloth behind which are neon tubes, providing secondary lighting. The wire cloth ceiling reveals the existing steel beam structure and the installations, giving the sense of enhanced height and lightness, while the work elements and the spotlights slide in the rails between the ceiling ribbons.
The upper level of the interior being exposed both to sun and the sight of the passersby, its envelope is protected by veils of translucent sandblasted sliding screens made of satinato glass, which can provide either a ballanced diffused light, or create more or less shadowy corners. At night, when looked at from the outside, they create a lantern-like image, glowing while floating above the square level. Silhouettes of the people in the interior can clearly be traced on the satinato screens, creating a theatrical effect. As the movie audience, after leaving the nearby theatre, passes by (they have to walk this path on their way out of the cinema), they are able to retain the magic for a moment, exposed to another kind of theatre, the Theatre of Shadows.  la coulisse (Fr.) = a sliding element; a stage scenery; a secret.
