earth sheltered underground hill house

mike
earth sheltered house under construction in Maine. Steel arch building on concrete foundation and block walls, sealed with tar-pitch, rigid foam insulation, thick polyethylene sheeting, a tough and non-biodegradable fibrous protective mat, and covered with less than a foot of soil and a suitable groundcover. Inside is spray-foam insulated and then finished with textured gunite, all interior wood is cedar and hemlock from the building site. Central fieldstone pillar houses the woodstove and serves a thermal heat bank in wintertime. Back wall is left off and floorplan is open, we'll be using a spiral staircase to ascend to the loft and will have an exit out the north side, on the loft level. With composting toilet, woodstove and solar power system working to provide us comfort without a huge impact, this house is projected to cost less than 25,000 to build. #earth_bermed_house #earth_sheltered_house #earthberm #earthbermeb #energy_efficient_home #energy_efficient_housing #geothermal #green #green_building #green_roof #hobbit_house #live_roof #living_roof #passive_solar #steel_arch_building #sustainable #thermal_design #udeground_home #undeground_house #underground #underground_home #underground_house #wonder_building
