This thesis is divided in two parts, both mutually important, the feasibility study and the personal experience living and working in Saudi Arabia. The feasibility study of a promotion in Jeddah, Saudi Arabia, Is a basic study of a promotion in North Jeddah, this project has the name of Al Sharooq, it’s a 180.875,00 m2 terrain where a complex of 112 buildings are projected, this 112 buildings are divided in 8 typologies which we will see afterwards. The study is composed by a study on the size of the project, a Market study, a study on the bill of quantities, a study of the location of the project, a financial study with VNP and IRR results from which we can positively approve this feasibility study, and a final evaluation of everything studied. The results of the financial study give us the exploitation of a 10 % of the promotion and an IRR (TIR) percentage of a 25,62% making the promotion sufficiently profitable, the cost of construction per square meter rises up to 3.561,31 SR m2. A little history of Saudi Arabia and its current situation, It’s king, laws, criminality, visas and working permits, but mainly my experience working in the kingdom, my experience living there and some insight of that country and future possibilities. It is mostly intended as a message to other students who like me finished their careers and are considering the kingdom of Saudi Arabia as a possible destination. Not as much as cultural differences study but more like how it feels to live in there, how things are, and how much your lifestyle could change when you are in there. Even so it is something I would have liked to have read before I went to work there. Objectives of the thesis on silver linings: *Get to know the way of working in Saudi Arabia. *Do a feasibility study in situ. *Define the economical and working situation of the country. *Study the possible future opportunities for expatriate students.  Mark the most important cultural differences with which a European worker should count with if he wants to come to work to this country.
