The characteristic regional expression of Kerala architecture results from the geographical, climatic and historic factors. Geographically Kerala is a narrow strip of land lying in between western seaboard of peninsular India and confined between the towering Western Ghats on its east and the vast Arabian sea on its west. Favoured by plentiful rains due to Monsoon and bright sunshines, this land is lush green with vegetation and rich in animal life. In the uneven terrain of this region human habitation is distributed thickly in the fertile low-lands and sparsely towards the hostile highlands. Heavy rains have brought in presence of large water bodies in form of lakes, rivers, backwaters and lagoons. The climatic factors thus made its significant contributions in developing the architecture style, to counter wettest climatic conditions coupled with heavy humidity and harsh tropical summers.
