The text Primitive Future, written by Sou Fujimoto relates architecture to the importance of lighting and materials, and how they drastically affect the function and atmosphere within of spaces.  Fujimoto describes gradation as the “key to future architecture”. Believing that “between white and the black there is an infinite colour range” (Sou Fujimoto, Primitive Future, 2008, P. 130). He believes that the gradation between spaces are affected by internal and external environmental factors that can create an infinite number of functions and possibilities within a space.  The Wall House located in Lampa, Chile, designed by FAR (Frohn & Rojas), highlights the importance of Fujimoto’s theory of gradation though the use of materials and lighting,  drastically affecting the structural layers and spaces in the building itself. Each layer offers a very specific structural, functional and atmospheric climate which contributes to the intelligent hierarchy of the building.  The hierarchy integrates gradation of the spaces within the building through the use of density in materials. Fujimoto describes the layers of gradation much like a cave, the mouth being the most public and brightest, while the darkest and most private spaces are in the rear of the cave. This similar context is connected to The Wall House.  Starting at mouth of the cave, the exterior layer of the building, “soft skin” is a fabric membrane that covers the building and filters out the solar energy hitting the structure, simultaneously allowing for plenty of views and natural light to flood the interior. The second layer consists of the “Milky Shell”, a folding translucent skin constructed of high-insulation polycarbonate panels, which filters the harsh Chilean sun, registers external shadows while simultaneously flooding the living and master bedroom with natural light. Travelling deeper into the cave, the third layer “Stacked Shelving” build from engineered wood, formwork panels and plywood allows for both public (kitchen and dining) to be revealed and private spaces (guest room) to be hidden within the structure allowing minimal natural lighting to enter each space through solids and voids. Continuing into the darkest part of the cave and the final layer “Concrete Cave” which consists of two introverted concrete bathrooms, the core of the structural system. Implying a cave-like atmosphere for the inner and most private domestic function of the building.  The Wall House uses lighting and material (density from thin to thick) to create a journey into the rear of the “cave”. Creating an ever-changing atmosphere in both public and private spaces the deeper you journey in to the house, highlighting the importance of gradation not only through lighting but also through materiality and circulation.  	 On a personal level, the gradation between public and private spaces through the use of light, material and circulation fascinates me. Depending on these factors, it allows an individual or a group to feel comfortable, safe and relaxed or the complete opposite. These internal and external environmental factors greatly affect each individual’s lifestyle, both physically and emotionally and understanding of local architecture itself.
