concrete with crushed river stone, coconut palm stem wood used in roof structures, cane (bamboo) used in walls and roof structures, etc.

The bricks are made by locals with local clay, cooked in handcrafted ovens (see **Figures 29** and **30**). A sample of solid clay bricks parts was analyzed in the Materials Laboratory of the Faculty of Architecture and obtained an average compressure resistance of 9.31 MPa (93.10 kg/cm<sup>2</sup> ), which complies with the Complementary Technical Standards [10], however, the furnaces will be improved for greater heat efficiency, lower consumption of firewood and adequate control of emissions during production.
