The architecture of Madagascar is unique in Africa, bearing strong resemblance to the construction norms and methods of Southern Borneo from which the earliest inhabitants of Madagascar are believed to have emigrated. Throughout Madagascar and the Kalimantan region of Borneo, most traditional houses follow a rectangular rather than round form, and feature a steeply sloped, peaked roof supported by a central pillar. In South Kalimantan, traditional houses are generally raised on piles and feature "house horns" formed by the crossing of roof support beams at each gable end. Traditional Malagasy houses are likewise often built on piles, and the tradition of house horns can be seen in some southeastern communities and in the wooden architectural traditions of the andriana noble classes of the Merina people of the central highlands.
