Houses built in stone masonry are found in rural and urban areas around the world. There are huge variations in construction materials and technology, shape, and the number of stories. In rural areas, houses are generally smaller in size and have smaller sized openings since they are typically used by a small family. Such houses are popular and built, where such stones are naturally available locally, and due to which the skilled labour to do the same is also available.
