The architectural design of the Marriott Restaurant is based on the transformation of furnishing elements in time and space. The primary transformable element is a membrane system composed by two types of curtains and positioned in correspondence to the tables: curtains in wood slats, in the outer part and fabric curtains on the inside. This double casing defines, during the day’s events, semi-private spaces (using curtains in wood slats) or totally private spaces (using curtains in wood slats and curtains fabric). The use of natural materials such as the wood and the fabric emphasizes the desire to create a welcoming environment and at the same time puts attention to a natural mutation. Other elements that give flexibility to the restaurant are the convertible tables through a telescopic system that adjusts the height of the plane support from breakfast to cocktail time. The project consists not only of a mobile dynamic system, but also of a fixed one, that accommodates bar, kitchen, bathroom and reception: services obtained in a curved and sinuous wall.
