Mud Hall is a project initiated by Harvard University’s 2012 Loeb Fellows to promote awareness about rammed earth construction and to challenge conventional thinking about green building. Raw earth is the most plentiful and sustainable building material on the planet, yet architects rarely incorporate it into their designs. To demonstrate the potential of mud and clay for everyday buildings, the Loeb Fellows are enlisting 25 students at Harvard’s Graduate School of Design to construct a rammed earth structure at the entrance to the school’s celebrated Gund Hall. Mud Hall is meant to offer an alternative to the current orthodoxy about sustainable construction. This blog will chronicle the evolution of the Mud Hall project, and offer detailed information about the rammed earth process.
