As a building material, cement is seen as a sign of wealth. The cities are rife with it, and all of the government buildings are constructed in cement. In the capital, it is easy to differentiate between buildings that were styled by Gabonese and those done by outside architects. In the villages, the architecture is different. The structures are impermanent. The most economical houses are made from mud and covered in palm fronds. There are houses built from wood, bark, and brick. The brick houses are often plastered with a thin layer of cement with roofs made from corrugated tin. A wealthy family might build with cinder blocks. In addition to the houses, both men and women have distinctive gathering places. The women each have a cuisine, a kitchen hut filled with pots and pans, wood for fire, and bamboo beds set against the walls for sitting and resting. The men have open structures called corps de guards, or gatherings of men. The walls are waist high and open to the roof. They are lined in benches with a central fire.
