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.
The school was built by NGO Lakshyam and Geeli Mitti. What makes it so special is that it was built using neither bricks, nor cement!
