Aircrete Domestead
Project Overview for AircreteDomestead
This is an open source project, sharing everything about how to build your own aircrete dome home. Status will be presented in the next post.
The location is in the western Ozarks. It is a heavily forested place, mostly oak, with some nice topography.
The main living area is a 30 ft inside diameter aircrete dome with 7-3/4 inch thick outside walls. The equator is on top of a 39 inch tall cylinder (the first 3 coarses of 13 inch tall blocks). The inside apex will be 18 ft 3 inches. There will be a loft to be used for an office. Above the center will be a cupola with plexiglass roof and screenedvents. It includes 4 arches on the perimeter for a large south facing window and passages to the bedroom (east), sunroom (west) and front entry (nne). There will be additional smaller windows. A wood stove and propane will be used for heat. A stained cement slab floor will provide natural cooling in the summer. AirCrete domes have very little air infiltration and this wall thickness provides at least R19 insulation, like fiberglass batts in a 2×6 wall. A heat recovery ventilation system will assure fresh air inside. It’s unlikely that AC will be required.
