A similar trend can also be seen on the west; however, a cinema was built in the opposition of housing units. Additionally, the road had expanded to connect the aforementioned constructions
Regarding the changes that took place in the north, it was clear that two smaller paths, each on both sides of the central road had been removed. At the central north, a yacht marina had been built along with the former sea while a semicircular road had been constructed to surrond this area. Many apartment units along with the newly made road had been made on the northeastern area, meanwhile the previous industrial area on the west had been replaced to adapt a multi-storey car park. It is also interesting that a swimming pool, park and multiple shops had been erected, which all had connected paths to others.
