9 Steps to build your Earthbag / Superadobe Hobbit House

1. Planning and Design

Sketch Your Dream: Start by sketching your hobbit house, considering its size, shape, and the natural landscape of your building site. Incorporate features such as a round door, circular windows, and a green roof.

Permissions: Check local building codes and obtain any necessary permits. Superadobe construction is unique, so consult with local authorities early in the planning process.

Choose the Site: Select a site that naturally blends with your hobbit house design. Ideally, a hillside location works best for creating that iconic earth-sheltered look.

2. Gathering Materials

Visit the Earthbag Store to purchase superadobe bags. You’ll need:

  • Superadobe bags (long, tubular bags made of sturdy, UV-resistant material).
  • Barbed wire (for layering between bags to prevent slippage).
  • Tamping tool (for compacting the earth within the bags).
  • A mixer (for preparing the earth mix).
  • Soil with clay content (ideal for filling bags).

3. Laying the Foundation

A solid foundation is crucial for any structure, including a hobbit house.

Excavation: Dig the foundation to the desired depth, considering the frost line in your area to prevent heaving.

Foundation Material: For a hobbit house, a gravel foundation can provide excellent drainage and a stable base. Lay a weed barrier, then fill with gravel, compacting it to create a level base.

Layout: Outline the shape of your hobbit house on the foundation using stakes and string. This guide will help you maintain the correct shape as you build.

4. Constructing the Walls

Superadobe walls are built by filling bags with a mix of soil and a small percentage of cement or lime for added strength.

Filling Bags: Mix your soil with water and a stabilizing agent (like cement) to create a damp, moldable mixture. Fill your superadobe bags using a bucket or chute, ensuring each bag is filled uniformly.

Laying Bags: Place the filled bags in a continuous coil, following the outline on your foundation. Each layer should be tamped down firmly to create solid, compacted walls.

Barbed Wire: After each layer, lay a strand of barbed wire before starting the next. This adds tensile strength and keeps the bags from shifting.

Door and Window Frames: Integrate frames for your round door and windows as you build the walls. Temporary supports may be needed until the structure is self-supporting.

5. Constructing the Roof

For the iconic rounded hobbit house roof, you can extend the superadobe technique to create a dome, or construct a wooden frame and cover it with earth.

Superadobe Dome: Continue the superadobe coils, gradually bringing them closer together to form a dome. This method requires careful planning to ensure structural integrity.

Wooden Frame: Construct a wooden frame for the roof, then cover it with waterproof material. Finally, pile earth over the top, planting grass or other vegetation for that classic hobbit house look.

6. Waterproofing and Insulation

Ensuring your hobbit house is waterproof and well-insulated is crucial for comfort and longevity.

Waterproofing: Apply a waterproof membrane over the roof and exterior walls before covering them with earth. This prevents moisture from penetrating the structure.

Insulation: While the earth itself provides natural insulation, additional materials like wool or recycled polystyrene can be used within the walls for enhanced thermal performance.

7. Interior and Exterior Finishing

Exterior: Shape the earth covering your hobbit house to blend naturally with the landscape. Plant grass, flowers, and shrubs to create a living roof and walls.

Interior: Apply natural plasters to the interior walls for a smooth finish. Install custom woodwork, cozy furnishings, and efficient lighting to bring your hobbit home to life.

8. Utilities and Services

Integrate modern conveniences such as plumbing, electricity, and internet without disrupting the hobbit house aesthetic. Consider sustainable options like solar panels, composting toilets, and rainwater harvesting systems.


Building a hobbit house with superadobe is a journey that demands creativity, patience, and a bit of hard work. By following these detailed instructions, you’ll create not just a unique and sustainable home, but a personal haven that reflects the harmony between nature and imagination. Remember, the key to successful superadobe construction lies in careful planning, attention to detail, and a passion for creating something truly magical.
