3| Drainage System
A house built on the side of a hill should have a very good system of water collection, and a solid and sturdy foundation. Otherwise, the water drained from the top of the hill can flood the court and break down the house foundation. Instead, a house built on top of sloping land is not at risk of flooding, but it should be built on a solid, flat surface, where there is no risk of landslides. Consolidation will be made through a retaining wall or terracing.
