Aleppo is Syria's second most important city, once called the "Jewel of Syria," this city could be the worlds oldest continuously inhabited one, the evidence of settlement goes back to 6,000BC, but excavations suggest it may have been inhabited 5,000 years before that. The ancient town in Aleppo has developed over the centuries. Residential neighborhoods have grown steadily and have taken various forms that have been influenced by several factors. The housing sector, the core of the city and the most important part of it, has suffered of many problems during this development. Although the traditional courtyard house, which is a common building typology in the old town, is one of the most sustainable housing systems, that regards the social values of the Arabic oriental culture. However, the development of the housing system in subsequent periods of the last century took a wrong turn. The erroneous imitation of the European styles and the misuse of technology without taking into consideration the climate effects of the surrounding environment and the social background of the population led to the production of rigid concrete blocks, that drained the city of its identity. Aleppo which have survived many conflicts over decades, is still alive but in ruins. After seven years of civil war, among the Syrian cities, Aleppo received the largest share of destruction, the housing sector has been hit the hardest. Whole neighborhoods were destroyed, leaving large areas of rubble and thousands of people homeless. More than 40% of homes in the city have been completely damaged. Now that the situation has relatively calmed down, these destroyed neighborhoods must be rebuilt soon, but this time properly and environmentally friendly, in a way to interact with the climate, society and history of Aleppo, to allow the residents to return to their home city. This research takes Aleppo as an example of a Syrian city. In the first three chapters of the book the city will be studied regarding its location, climate, history and the development of its housing typologies to take their current forms. In the last chapter, considering the facts and information in the previous sections of the study, a model of post-war housing typology will be defined. This model will try to solve the problems of the current housing system, based on several climatic, economic, social and historical aspects and takes the traditional courtyard house as an inspiration. These aspects form the foundations to design the new typology, that offers in a short time the residents of Aleppo, who lost their homes during the war, a new way of living, which is suitable for the climate there and takes in consideration the social and historical background of the Syrian society. The HOME project is a realization of these principles, as a prototype of the future housing typology in the city of tomorrow in Aleppo.
