Sederhana is another building from the whole of Piyandeling complex. This building is a one-floored building, just like its name, which is more simplistic than Sumarah and Kujang.
The building is constructed with stone as a podium. Still using bamboo as its main materials, bamboo is used to construct its roofs. The method to make its roof is called Talahap which is a traditional bamboo construction made from layering it on top of each other. The bamboo would then be layered with a waterproof membrane and nipah.
