The Tipu Sultan Merkez School in Punjab, Pakistan has a new sustainable building that was designed by German architects Roswag Seiler and built by locals. Using locally sourced and low-impact materials, the shelter was fashioned from cob, bamboo and mud. Cob is widely used in Pakistan, and is a material made from clay, sand, water and straw. The concoction can easily be mixed by bulls, and once set, works as a natural insulator that keeps humidity at bay and interiors cool.
