The project here is the design of a private residence on a 718.3825 square meters of land. The location of the site is in Taraz, Pétion-Ville and it is a residential area with a particularly wet and green vegetation. We note that it is a sloping land of more than 10% and that for the realization of this project we will make a report of balance embankment / excavation in order to reduce the costs of construction: That's why we chose the concept in cascade.
