The project is located on a wide green topography at north surrounded by main road, at west surrounded by Esenler Wedding Hall Complex. The main tendency to the concept of fairground is flexibility. Except exposition dates, the area is used as parking-lots which are melted into landscape. Furthermore, the area can be perceived and used as a square before and after exposition dates. The structures which care for the ecosystem functioning are settled under the earth in the project area. The apex of the hill is abandoned for a green roof and a public square. The project is proposed that expo area and wedding hall can be connected by a fluid landscape.
