The Gaza Strip is often described as the “world’s largest open-air prison” due to the virtual immobility of its population. The 1.4 million residents (three-quarters of them refugees and a half under the age of 14) are surrounded by fences and walls to the north, east, and south, and have limited access to the Mediterranean Sea to the west. Living in an area only slightly larger than twice the size of Washington D.C., but with a population density three times that of Manhattan, its inhabitants have witnessed a turbulent history: starting with the Egyptian occupation in 1948, the Israeli occupation in 1967, and finally a unilateral withdrawal of Israel’s forces and settlers in 2005. Therefore the project is to improve the living condition, in the meantime, it needs to fulfil all the population in the area.
