Kota Blue Stones

In green architecture, using local materials is an important criterion, but the idea of local has often been debated. If cement is locally available, does it become local? What if the local product is costlier than an out station product? Kota stone is a good case in point. This excellent flooring material travels all over India from Rajasthan, hence theoretically not so eco-friendly, but being natural lime stone and suited to a variety of conditions, it fares better than most local options.
