Papua New Guinea stilt house is a unique architecture constructed by Motuans, a native inhabitant in Papua New Guinea. Papua New Guinea is a country with high mountains, forests, lowlands, swamps and coral beaches. The mountainous part of the country is called the Highlands and the low land part which meets the sea is called the Coastal region.

The Motuans live in villages along the southern coastal area of Papua New Guinea . They live in houses built on stilts over the sea. Even today they still like to build their houses over the sea. The stilt houses can last from 20 to 30 years. This will count on the sort of lumber used for the posts, and hence the type of tree they choose is of great importance. The Motuans do not go into the forest to chop any big trees down. They have to chop the trees that can resist erosion and propulsion of waves. If that is ignored, they will probably replace the posts quite often, every five or so years.

Building method

The height from the ground to the floor of the house is about 3.5 to 4 metres. This allows for the water level at high tide. How long it takes to build a house depends on the availability of materials. In the beginning the posts need to be fixed into the ground, so, in this case, the sea has to be first at a reasonably high level to allow men to put the posts up. It takes all men in the village to help put up the posts because the houses are quite gigantic in size.

To erect one post requires about twenty men. Moreover, before the post is put up, the end that is to go down into the seabed is sharpened so as to allow it to penetrate easily. The 20 men divide themselves in half. They tie a rope around the post. Half hold onto one side while the other half hold the opposite side. The place where they want the post to stand is marked.
