How Do You Build a Straw-Bale Home?


Quick Answer

Dig trenches where you plan to build walls, ensuring they are wide enough to accommodate flat-laying bales and deep enough to reveal sturdier ground under the topsoil. Fill the trenches with gravel, and consider placing two layers of gravel-filled bags atop the foundation to keep the bales off the ground. During local harvest time, purchase two-wire or three-wire straw bales that have been kept dry, and stack them to build the walls. Leave gaps for windows and doors, adding wood frames to the spaces to hold the bales in place. While stacking, anchor the bales to each other using wood or bamboo stakes, ensuring each stake penetrates at least two bales.

Create a frame for the roof using 2x4 lumber, and cover it with plywood sheets. Waterproof the roof with pond liner before adding a layer of topsoil, if desired. Cover the walls with stucco or lime plaster for weather-proofing and fire resistance. Add doors and windows to finish the straw bale home.
