This is why electricity bills are lower in Bangladesh. Usually roofs are built by pouring solid concrete directly, but with this method small plastic pipes filled with soil are arranged on the roof before the concrete is poured. Once the concrete sets, round openings remain. Glass is fitted into these openings, letting natural sunlight flow into the house. This makes the interior brighter and gives the home a luxurious feel. You'll truly be amazed by the creativity of these people in Africa. Many can't afford expensive tiles for their courtyards, so when they pour concrete, they use molds to create different designs that look just like tiles. Once the concrete dries and is painted on top, it becomes a strong courtyard that looks luxurious at a very low cost. Unbelievable! This African technique can save you a lot of money. While we install expensive tiles in our courtyards, people there pour concrete directly onto the ground and use a special tool to create tile-like patterns. Within a few hours, the concrete dries and then it's beautifully painted. This way, a strong, durable, and truly luxurious-looking floor is made at a very low cost.
