Choosing the Right Location
The long side of the Walipini should face north (in the northern hemisphere) to maximize sunlight. This orientation ensures that the greenhouse absorbs the most heat during the day, which is critical for maintaining a stable internal temperature.
Also, you need to choose a location with well-draining soil to prevent waterlogging. A natural slope is beneficial, as it can aid drainage and make the structure easier to build. Be mindful of nearby trees or structures that might cast shadows.
Determining the Size and Depth
For a family garden, a Walipini that’s 10 feet wide and 20 feet long is a good starting point, but you can adjust the dimensions depending on your needs.
You also need to notice that a depth of at least 6 feet will keep the temperature inside the greenhouse stable, even during cold winter months.
Materials Needed
You need to prepare:
Excavation tools: shovels, pickaxes.
Retaining wall materials: Concrete blocks, bricks, or large stones.
Roofing: greenhouse plastic, polycarbonate panels, or glass.
Structural supports: Wood or metal beams.

Step 1: Excavation
You’ll need to excavate the soil to a depth of around 6 to 8 feet, depending on your climate and growing needs. As you dig, ensure that the floor is level to allow for proper drainage.
