The life of Indians is centered in the family. Extended families often live together, with two or more adult generations, or brothers, sharing a house. In much of the countryside, neighboring houses share a wall, so from the street one sees a continuous wall pierced by doorways. In other areas, in the south for example, the main house will have a veranda on the street, with an open courtyard behind. As farmers prosper, they change from adobe construction to brick plastered with cement, and from a tile or thatch roof to a flat concrete or corrugated metal one. Most home activity is outside in the compound courtyard or on the verandas of the house.
