Question

house is build on poles​

Answer 1

Stilts are poles, posts or pillars used to allow a structure or building to stand at a distance above the ground. In flood plains, and on beaches or unstable ground, buildings are often constructed on stilts to protect them from damage by water, waves or shifting soil or sand.

Stilt houses (also called pile dwellings or lake dwellings) are houses raised on stilts (or piles) over the surface of the soil or a body of water. Stilt houses are built primarily as a protection against flooding; they also keep out vermin. The shady space under the house can be used for work or storage
