I have established the conceptual design of the building for Prokon-Ekon Headquarters in Kazan, Ankara, Turkey, 2011. The building reflects the power of a group of companies which not only prepare architectural and engineering projects, but also provides consultancy, establishes contracted construction works of large scale works, and has a factory of steel construction just besides the new headquarters. That is I have intended to reflect this united power with an ambitious structure as the welcoming face of building. I have drawed application drawings with Y. Mimar Tuba Altansunar. The building is one of a green design, and a candidate for LEED Platinum certificate. I have designed the building to be a sustainable one and coordinated the LEED process of building.
