There are two types of Ghanaian traditional construction: the series of adjacent buildings in an enclosure around a common are common and the traditional round huts with grass roof. The round huts with grass roof architecture are situated in the northern regions of Ghana (Northern, Upper East and Upper West regions), while the series of adjacent buildings are in the southern regions of Ghana (Ashanti, Brong-Ahafo, Central, Eastern, Greater Accra and Western regions).
