In fluid dynamics, wind waves, or wind-generated waves, are water surface waves that occur on the free surface of bodies of water. They result from the wind blowing over a fluid surface. Waves directly generated and affected by local waters or wind wave system and the result of the forms are amazing. Okeana Structure has been inspired by ocean wave lines and forms. There are many types of wave forms which called that spilling, plunging, collapsing and surging. We have studied these wave types and converted lines-forms to architectural forms. And we have created multi use structure form which provide private, semi-private and open areas that can be changes according to functions. Okeana multi-use structure can be use for exhibitions, meetings, presentations, fair or concert events etc.
