Beylikdüzü feels newer and more spacious than most of Istanbul. Residential sites often come with pools, playgrounds, parking and security, and the seafront in Yakuplu and the district's parks give families room to breathe. The Metrobus and the E-5 connect the district eastwards to the rest of the city; at rush hour the trip into the centre can be long, so try it before you decide.
What to check
Many projects look alike on paper, so compare the developer's delivered work, the build quality and the monthly site fee (aidat), not just the floor plan. Check the building permit date and earthquake compliance, the iskân (occupancy permit) and the walk to the nearest Metrobus stop. See current apartments in Istanbul and new projects.
