Solar Pit House

Solar Pit House (click to enlarge)

Specifications: 1,127 sq. ft. interior living space, 441 sq. ft. interior greenhouse, total = 1,568 sq. ft. interior, Footprint: 36’x53’

Description: This modern solar pit house is based on the traditional pit house. The construction is much the same. Additional ‘modules’ have been added to create an elongated rectangular design for added living space and windows added on the south for solar gain. Each module is based on wood posts set in geopolymer or concrete footings. Wood beams approximately 10”-12” diameter are joined at the posts with half lap joints and pinned in place with rebar or logging spikes. Smaller poles around the perimeter lean against the beams. 24” wide earthbag walls with a reinforced geopolymer or concrete bond beam rest on rubble trench foundations.

Triple Dome Survival Shelter

Specifications: Three 16′ interior diameter domes with 603 sq. ft. interior, 3 sleeping lofts with 312 sq. ft., total 915 sq. ft. interior, one bedroom, one bath, Footprint: 38′ x 38′

Description: This Triple Dome Survival Shelter provides much more space than my first earthbag survival shelter. This design is for long term survival for a family. It is earthquake and fire resistant, bullet and nuclear fallout resistant. It is built above grade to reduce risk of flooding. Features include buried cistern between the domes, plenty of storage space, vaulted entry with bullet resistant cellar door. Let’s hope for the best, but it’s also prudent to be prepared for the worst.

Spiral 2 Earthbag House

Spiral 2 Earthbag House (click to enlarge)

Specifications: 740 sq. ft. interior, 2 bedroom, 1 bath, Footprint: 31′ x 40′ plus buttresses and covered porch

Description: Spiral 2 is a variation of my first spiral house — Spiral Earthbag House. This unique, almost Hobbit-like earth-sheltered spiral design includes a large grow bed, exposed timber ceiling and living roof. Ample light is provided by the window wall next to the grow bed, window and door glazing, and suntubes. Distinguishing features include two bedrooms, masonry two-way fireplace, covered porch and cool pantry for storage of food (no electricity required for refrigeration). An alternate roof plan is available for building with TJIs where wood poles are not available. There’s even a door planned in for future expansion. This home meets zero energy standards, and is now one of my favorite.

Earthbag Survival Shelter

Specifications: 20’ DIA (314 sq. ft. interior plus pantry), Footprint: 23′ x 31′

Description: This round earthbag shelter for up to 4-5 individuals is designed for survival through disaster, plague, etc. It is low cost, durable and practical. This shelter is designed for DIYers on a tight budget who will do most everything by hand. Instructions include numerous key details not evident on the plan: venting, roof framing, how to reduce excavation by 50%, drainage, water supply, etc. I have not seen a better, more practical survival shelter plan.
