The project responds to the question of how visual work can solve a theoretical problem. Here, the visual intervention relates to an architectural element, a wall. This project is a full-scale experience of the attention paid to an architectural detail. The aim is to invent a rational yet sensitive space, free to those who inhabit it. The project has been designed as an interior framing, halfway between wall fresco, mashrabiya, claustra, stained-glass panel and mirror. This window of contemplation creates the atmosphere of the place/ It plays with the light to offer different interiors. In this imaginary nature that fills the space, the subject explores within the landscape through its reflection. They are central to the work.
