I Spent 279DAy Build A Secret Hidden Underground Swimming Pools

Welcome to Survival Builder! In this video, we reveal the full journey of how we spent 279 days building a secret underground house with private swimming pools, using only natural materials, traditional techniques, and pure dedication. 🔨 Step-by-Step Build – Behind the Scenes This project was made by a 3-person team — two builders and one cameraman, working together every single day to bring this hidden underground paradise to life. Here’s how we did it: 🪓 Step 1: Planning and Digging (Days 1–30) We first chose the perfect hidden spot, away from any roads or urban areas. With handmade tools, we began digging a 5x5 meter square underground base. This took weeks of hard labor, removing soil and shaping the space. 🏗️ Step 2: Structural Layout (Days 31–60) We shaped the walls, roof supports, and entrances. Using clay, mud, and natural stone, we built a sturdy and insulated structure that could hold up underground without collapsing. 🧱 Step 3: Wall Building & Roofing (Days 61–120) Walls were layered with a mixture of mud and straw. The roof was built with wooden logs, covered with bamboo and dried leaves for support and camouflage. We added a skylight to let sunlight in during the day. 💦 Step 4: Pool Construction (Days 121–180) Next came the pool! We built a compact, elevated pool using waterproofed clay and natural sealants. The green finish adds to its unique underground aesthetic. We tested and filtered the water to make it clean and swimmable. 🔥 Step 5: Heating & Interior (Days 181–240) We added a small fireplace/oven to heat the space during cold nights and cook food. We also carved out alcoves and built natural shelves for tools and storage. Some lights were added using torches and solar lanterns. 🎥 Step 6: Final Touches & Filming (Days 241–279) While two of us worked on finishing touches, our cameraman documented every moment. From building details to testing the pool, we wanted to make sure we could share the full journey with the world. 💬 Why We Built This We wanted to challenge ourselves to create something beautiful, hidden, and functional — using only our hands, natural materials, and survival techniques. No modern machines, no shortcuts. This Build is not just a house, it's a survival space, a relaxing hideout, and a symbol of patience and creativity.
