Full work of interior architecture which also made the firm's corporate image. Parts and elements of the optics have been designed to incorporate a full versatile program (repair, assembly, warehouse, toilet, office, retail outlets, office, shop window ...) in the 37 square meters measuring local. The space is divided into two zones: a band that runs the length of the side of the store to meet the control of vision autorefraction, whose fund is used also as an office, and a space distributed around a core formed by the central counter and the toilet. The separation between these parties is not opaque, allowing, if desired, an overview of the whole. It is a mechanism in which the majority of parts (valves, hinges, handles, mirrors, furniture, displays, lighting, mechanisms ...) were designed specially and made by hand, so that they could work in coordination. The materials are kept in their natural, untreated or uncoated.
