This is what the natives in Culasi see before they go to bed and when they wake up. This is a picture of a ceiling of a nipa hut or bahay kubo. It's made from bamboo and nipa leaves tied together to form a roof. It provides cooling during hot spell, and some water when it rains. The latter feature is not always welcomed by those living under this roof. It's not very sturdy and usually last for only a few years. The materials are indigenous so it can easily be replaced.
