Our design for AMERICAN AIRLINES and IBERIA, two-stage project, forms part of the expansion and refurbishment of Terminal C of the Ministro Pistarini International Airport in Ezeiza, Buenos Aires. The lounge has 124 seats in the first stage. The materials were selected to provide a general relaxing and calm atmosphere, characterized by two horizontal plans, floor and ceiling, such as continuity and white colour. The customized furniture made with corian highligts the color of the floor. Our proposal organises and orders the space by means of a central geometric core, whose undulating shape compresses and expands the space between the existing glass façades. This creates separate areas within the lounge complex to meet the tender requirements. This central element clasps the wet areas and technical installations within its structure, as well as those requiring a degree of privacy or isolation from noise, such as toilettes, showers, kitchen or workcenter. This undulated and continuous part is clad in oak and contains a line of LED lights, energy efficient. All other facilities are set along the façades of the building and allow passengers to enjoy unobstructed views over the airport. There are no floor-to-ceiling construction elements which may interrupt the global perception of the space or disorient the user. The design, soft and sinuous, is reminiscent of the fluid trajectory of airborne objects and brings to mind the very essence of airlines: flight.
