Underground Homes – Good or Bad? Excavation — Crews excavated for the placement of five interconnected Monolithic Domes for this underground home in Buffalo, Texas. Foundation — When completed, the owner of this underground dome-home will have a living area of 2,729 square feet. Five Interconnected Airforms — The five domes will encompass three bedrooms, two baths, office, kitchen and areas for entertaining, relaxing, dining, laundry and storage. Weight-bearing Capability — Domes can efficiently bear the weight of being buried. The heating and air conditioning ducts for this underground home are housed outside the dome shell. Invisible Dome-Home — Once this Monolithic Dome home is completed and covered it will become invisible. Tunnel — This unfinished, corrugated steel, underground tunnel will be finished with a concrete pathway and lighting. Going in! — Tunnels provide the only way to enter this totally underground Monolithic Dome home. But once inside, most people are neither overly conscious or uncomfortable about being underground.
