Cob : This is a natural building material i have explored for a detailing project on using natural building material to design a hut or shelter in Addo.
This was actually used in the past and is now being used in these modern time innovatively. From all the research that i've done, this is my understandig of the natural material: Cob is a mixture of sand, grass and water. It's considered an earth mixture. Generally cob wall are very thick,and this provides thermal mass to the structure, hence this works well as "sustainable and ecofriendly" ways of construction.

People have discovered that not only does cob have a sustainable function, but it is also cost effective. There are ways to which one can use the material in a creative way. For example : The image above shows glass bottles fixed in the cob wall, and artists have alo found a ue for this natural material by using it for sculptures. this material can be quite innovative when used in the correct design perspective.
