Make sure to slope the back wall higher than the front, this will create the angle needed for the sloped roof, which is essential for maximizing sunlight and ensuring proper temperature regulation inside.

Step 2: Building the Retaining Walls
Lay concrete blocks, bricks, or large stones carefully to create walls that are sturdy enough to hold back the pressure from the surrounding earth.
For additional insulation, you can add a layer of straw bales or earthbags between the walls and the surrounding soil to protect your plants from outside temperature fluctuations.

Step 3: Constructing the Roof Frame
The roof should be slanted at an angle of about 35 to 45 degrees to capture as much sunlight as possible, especially during the colder months.
You can use wooden or metal beams for the frame, making sure they are sturdy and spaced evenly across the structure to support the weight of the roofing material.

Step 4: Installing the Transparent Roof
After building the roof frame, you’ll need to cover it with a transparent material like greenhouse plastic, polycarbonate panels, or even glass.
As you install the roof, seal all gaps and edges carefully to prevent air drafts or leaks.
