Hello to all the great people of Alaska. I am a new comer to the forum and I am looking for your help and expertise to build an off grid earthen type cabin on my remote property on the Kenai peninsula. I plan on building it in the ground below grade. The earthen walls will be 12" thick, floor 12" thick earthen roof 2' thick. I plan on using a concrete thermal break and foam board between my walls, floor and roof from the surrounding earth to stop energy loss back into the environment. I plan on using glacial silt for the earthen material. My hope is to have walls floor and ceiling that will be able to hold thermal energy in the thermal mass of the walls floor and ceiling thus reducing the energy requirements to heat the cabin. The area is free from perma frost (one less problem for construction and excavation). The interior dimensions I am looking at are 8' ceiling height, 16' wide x 30' long. It will be a 4 season cabin with wood heat, propane stove, solar & wind power for electrical needs with back up gen, composting toilet, well water via hand pump self draining.
By the way the build location is 15 miles from the nearest road 30 miles from the nearest town. I look forward to all your comments finger pointing and laughter.
Thanks in advance for all your help
