Double Unit Ecoresort

This ecoresort design joins two earthbag roundhouses with private baths between. (click to enlarge)

Specifications: Two 16′ diameter roundhouses = 402 sq. ft. interior plus 80 sq. ft. baths, total 482 sq. ft. interior (241 per unit), 1 bed, 1 bath per unit, Footprint: 19′ x 49’

Description: This ecoresort design joins two earthbag roundhouses with private baths between. The roof extends over the porch to create a shaded area with benches for relaxing. Windows on all sides provide optimum ventilation and thermal comfort (15 degrees F or 8 degrees C cooler inside than out). Glass block and bottle walls add a splash of color and fun. Thatch could be used, although metal roofing is more durable and fire resistant, requires less maintenance and allows for roofwater collection. With just a little modification, the two units could be joined to create a home by enclosing the porch as a passageway, converting one bathroom into a laundry room, and deleting one kitchen.

When something works exceeding well, it makes sense to pursue similar options. I’ve been saying for some time that earthbag roundhouses are the simplest, fastest, easiest, most practical way to build with earthbags. (Domes are great in some ways, but they have certain design limitations and are not the best choice for our hot, rainy climate. Square and rectangular designs have some benefits, but tend to be a bit boring, especially for an ecoresort, and long straight walls require additional support.)

That’s one reason I’ve created designs such as Two Roundhouses with Greenhouse, Three Roundhouses Design, my Hobbit designs, as well as numerous other roundhouse designs at Earthbag House Plans. (You can easily browse all roundhouse plans by selecting ‘Round’ in the Category menu on the right side of the page.) Note — most people end up modifying these basic designs to meet their needs, which can easily be done for a modest fee.

Each step of construction is explained in this Earthbag Roundhouse Instructable.

HNC Earthbag House

HNC Earthbag House (click to enlarge)

“The Haitian National Congress (HNC) asked me to conduct training next May for bright and eager Haitian adult citizens who want to become entrepreneurs, nudge their country more toward functional democracy, learn problem solving skills and learn free enterprise practices that will increase their personal income. These trainees will then return to each of Haiti’s 10 departments to teach others about developing cottage businesses, managing money, establishing new markets, increasing vegetable production and more.

Haiti needs more housing stock. For the individual Haitian, owning a home and building equity in it is a way to better oneself financially. HNC is working with folks who have minimal income. HNC encourages them to build wealth which helps the country build a stronger economy. That leads to more jobs, more children getting educated, better health care, etc. To have value in the housing market, they need a house that is modern (plumbing and electricity), durable (earthquake and hurricane resistant) and of course, affordable. With a modern and durable house as collateral you can borrow money to start a small business. Lack of access to capital is a major barrier in the third world to individuals lifting themselves out of poverty. Earthbag houses are perfect. Hands on learning how to build an earthbag house will be an important part of the HNC training. The trainees will learn, and they will in turn train others in earthbag building. Modifications can be made in the field in response to local feedback.

Dr. Owen Geiger took my basic ideas, enhanced them greatly and developed an attractive plan. It is a durable and leak proof ‘core house’ with a multipurpose room (kitchen and living room), bathroom and bedroom. There is a covered, raised, and railed front porch for Haitian style outdoor living and for social gathering. Also, Dr. Geiger designed the walls a bit higher than 8’, dropped the ceiling slightly and put two ladder accessible lofts above. There are covered porches around the entire house that can serve as outdoor cooking, food preparation and work areas. They can also be easily converted into additional rooms. HNC and I are happy with this earthbag house plan that offers so much flexibility. The owners will have several options for sleeping, storage and work areas. While the disaster resistant core house remains the same, the lofts and porches allow each family to set up the house just the way they like it in order to meet their specific needs.”

Free Economizer Earthbag House Plan

Free Economizer Earthbag House Plan (click to enlarge)

Specifications: 448 sq. ft. interior, 1 bedroom, 1 bath, Footprint: 19′ x 31′

Description: This plan is designed to be compact and efficient. Most houses this size do not have as many features — washer/dryer, wood stove, and modern kitchen and bath. There are even two closets. An archway separates the bedroom from the main living area, yet maintains a sense of privacy with a room divider. Note: this plan is listed in the free shelter category.

Torus Design with E-Cat/LENR Home Energy System

Torus Design with E-Cat cold fusion energy generator (click to enlarge)

Torus Design floorplan (click to enlarge)

Specifications: 2,224 sq. ft. interior, 564 sq. ft. greenhouses, 1,520 sq. ft. courtyard, each side has two bedrooms, two baths, Footprint: 74’ diameter not including 8.5’ wide greenhouse

Description: The Torus Design is the first home to my knowledge that is specifically designed to utilize cold fusion generation. When LENR reactors come on the market (hopefully next year), they could be coupled with a micro-CHP cogenerator to produce both heat (radiant floor heat, in this case) and electrical power. The house concept was inspired by the movie Thrive, which outlines ways of creating prosperity and equality in the world. Lack of energy is at the heart of many of the world’s problems. Clean, affordable, sustainable energy would likely raise the standard of living for mankind by helping to alleviate poverty, hunger, lack of clean water and more.

The Torus Design brings together three emerging trends: increasing self sufficiency — including renewable energy and food production, families moving back together to save money, and sustainability. These trends are evident in the growth of home gardens, organic food, green building, eco-conciousness, off-grid homes, do-it-yourself attitudes, and cost cutting strategies such as bartering and trading for goods and services.

The current version could be used as a duplex (rent the other half to slash your bills). You could split costs with a friend or family member and share the courtyard. A lot of people can no longer afford their own home, so this design offers a potential solution for families to move in together. The design could be customized for large families.

Options not shown: cisterns on the exterior and courtyard, underground Earthbag Survival Shelter with optional escape tunnel, Cool Pantry, rainwater barrels, food forest surrounding the home.

Plans can be ordered through DreamGreenHomes.com (The Torus Design should be posted there shortly.)

Three Roundhouses Design

Three Roundhouses Design (click to enlarge)

This plan illustrates what I think is the simplest, easiest way to build an earthbag home: build in stages, one roundhouse at a time so you can pay with cash and move in right away. It’s far easier to start small and add on later than jump right into building a large home that could take months or even years. I’ve talked about this a lot on our blog, but this is my first plan designed specifically for building in stages. This is becoming one of my favorites. What do you think?

The Three Roundhouses design combines:
– Hobbit House (starter house in this design): 471 sq. ft. interior, optional 471 sq. ft. loft, one bedroom, one bath, Footprint: 27′-6″ diameter
– Roundhouse Studio (master bedroom in this design): 177 sq. ft. interior, fold-out bed, 1 bath, Footprint: 18′ diameter, plus buttress
– 33’ (10m) Roundhouse: 855 sq. ft. interior, 1 bedroom, 1 bath, Footprint: 36′ diameter
Total living space: 1,503 sq. ft. interior

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.

This is nearly the same design as my 33’ (10m) 2-bedroom Roundhouse except the roof. The walls have a slight taper to create a castle appearance for the Dome Fort I’m currently designing. In addition, a second floor with slot windows has been added.

Specifications: 855 sq. ft. interior, 2 bedroom, 1 bath, 855 sq. ft. upper floor, total = 1,717 sq. ft. interior, plus roof deck, Footprint: 36′ diameter

Description: 10 meters (33’) diameter is the maximum size of a round earthbag structure before needing buttressing (unless you use reinforced earthbags). This spacious design features a large master bedroom with desk and walk-in closet, efficient kitchen and south-facing window wall for excellent solar gain.
