Instructions

• Step 1: Drive poles into ground Drive several straight tree limbs at least 1 foot into the ground every 8 to 10 inches along a single line. This is your first wall line.
• Step 2: Make mortar Make mud mortar by mixing together two parts clay soil, two parts water, and one part dead grass in a large pit.
• Step 3: Collect rocks Collect rocks to reinforce the walls and allow the mud to adhere vertically.
• Step 4: Layer rocks and mortar Layer the rocks and mortar against the poles to keep the wall straight and keep it from caving in.
• TIP: Make the wall thicker at the bottom than the top to provide more stability.
• Step 5: Build remaining walls and roof Build the remaining walls, and then lay more limbs across the tops of the walls and layer saplings or large leaves to construct the roof.
• TIP: Smear mud onto the thatched saplings and then sprinkle fertile soil over the roof to encourage grass and moss to grow for a weather tight seal.
• Step 6: Seal cracks inside Slather the mud mixture over the inside to seal cracks or weak spots and to give the walls a smooth texture.
• FACT: In 2008, an ancient Egyptian town of mud brick structures, dating back to 2400 B.C.E., was uncovered in near perfect condition.
