A sod house, also known as a “soddy,” is an environmentally-friendly and economical dwelling made from layers of sod – that is, grass and the soil held together by the root system. These houses have been used for centuries by various cultures around the world, particularly in areas where lumber and other resources were scarce. If you’re interested in building your own eco-friendly home, here’s a step-by-step guide on how to construct a sod house.

Step 1: Choose the Location

The success of your sod house greatly depends on its location. Ideally, you should choose flat or gently sloping ground with good drainage to avoid issues with water seepage. Additionally, ensure there is an ample supply of soil and grass suitable for construction nearby to reduce transportation efforts.

Step 2: Outline the House

Mark out the perimeter of your desired sod house using stakes or rocks. A typical sod house can be rectangular or square in shape, generally measuring around 16×20 feet. Remember to plan out windows, doors, and additional support features like internal walls.

Step 3: Excavate the Foundation

Dig a trench about one foot deep and one foot wide along the perimeter of your house. This foundation trench will help secure your walls and provide better insulation against water seepage.

Step 4: Cut and Prepare Sod Blocks

Using a sharp spade, cut into the nearby grassy area to remove sod blocks for building your walls. Each block should measure about 12 inches long, six inches wide, and four inches deep. Keep in mind that larger sod blocks will provide better insulation but can be more challenging to handle during construction.

Step 5: Start Building Walls

Begin laying your first row of sod blocks in the foundation trench with their root side facing downward. Interlock each corner tightly by staggering blocks on each subsequent layer. This will create a more stable and robust wall structure.

Step 6: Install Door and Window Frames

Once you have built your walls up to about three feet in height, it’s time to install the door and window frames. While door frames can be constructed from wood or metal, window frames should be made of wood to accommodate the flexible nature of sod walls.

Step 7: Continue Building Walls

Keep building up your sod walls, ensuring they remain plumb (vertically straight) and appropriately reinforced throughout the process. Ideally, sod walls should be around seven feet high with a slight incline inward for added stability.

Step 8: Build Roof Support Structures

Install wooden beams or rafters extending from one long wall of the sod house to the other. These structures will provide support for the roof while allowing for air circulation within the house.

Step 9: Construct Roof

Cover the support beams with a layer of wooden planks, followed by a waterproof roofing material such as tar paper. On top of this waterproof layer, add another layer of sod blocks with their root side facing upward. Lastly, cover the roof with grass or turf to blend seamlessly with your wall structure.

Step 10: Final Touches

Shape the edges of your sod house to eliminate any overhanging grass or dirt that could let water in during heavy rains. Install any required interior features like benches, shelves, or a stovepipe and remember to give your new sod house time to dry out before moving in.

In conclusion, building a sod house is an affordable and environmentally-conscious alternative to modern housing options. By following these ten steps, you can create your own sustainable living space that not only provides insulation against harsh weather but also helps preserve valuable resources like lumber.
