Climatic conditions are a major concern while building earthen structures. Typically, earthen buildings are found in areas where the climate is dry and arid. Wayanad, where Banasura Hill Resort is located, has a tropical wet climate - also known as a tropical monsoon climate - with an annual average rainfall of well over 2,300mm. While the heavy monsoon rains are responsible for the tropical rain forests and the rich bio-diversity found in these parts, building a rammed colossal earth structure under such climatic conditions is a challenge. Despite this, construction of the main building was completed within 18 months.
