There are two sides of Istanbul; the European side and the Asian side. To be clear, the European side is considered better than the Asian side, owing to the majority of the population, the historic places, most of the best universities, and the most of business and commercial life are concentrated in the European side of Istanbul. Moreover, the Golden Horn, which is called in Turkish “Haliç” shaped on the European side, and considered the major urban waterway and the primary inlet of the Bosphorus in Istanbul. It is not far away from the golden horn, there are two important districts called Gaziosmanpaşa and Kağıthane. Gaziosmanpaşa is located on the European side with a population 400,000 and mixture of people belongs to different ethnics and religions. While Kağıthane is also located on the European side and considered one of the largest regeneration and real estate development districts in Istanbul. In the same context, Başakşehir as a city planned in luxury standards, in addition to its unique location, which is close to the most important facilities such as, Istanbul airport, Ataturk airport, the biggest city Hospital and public transportation, becomes one of the most promising regions in Istanbul.
