4 - The coastal buildings, which are called Vasemasema, have gabled or slightly hipped roofs, are rectangular in ground plan and have an entrance on the longer side. With time additional, doors were built and some were even built with windows, although this seemed to be a historically very recent practice linked to European influence. The houses usually featured two main piles at the gable ends or king posts on tie beams within the building and the main piles could be set in the plane of the shorter end walls, then the roof was gabled, or somewhat toward the inner part of the house, then the building would have a slightly hipped roof. The walls were made of different materials and methods than in the highlands; often they were thatched with leaves or branches of certain trees.
