This is a wall being built in the neighborhood. This also is block and cement, but here they have covered the block with a smooth layer of cement. This is how the walls in a house are also finished. It’s funny. Sometimes you see the basic blocks (particularly in walls like this) and it looks like a mess, not very straight or neat, but in the end they cover it with cement and it ends up looking perfect! These piles of blocks, cement, and gravel are sure signs that some sort of construction is going on in that house, and are common sights all around our area.
