How to Construct a Perimeter Wall:

1. Planning and permitting. 
   Before you start construction, you need to get the necessary permits from your local government. You also need to plan the design of the wall, including the materials you will use, the height and thickness of the wall, and the foundation.
2. Excavation. 
   The next step is to excavate the foundation trench. The depth of the trench will depend on the type of soil and the height of the wall.
3. Foundation.
   The foundation is the base of the wall, and it is important to make sure that it is strong enough to support the weight of the wall. The type of foundation you use will depend on the soil conditions.
4. Wall construction. 
   Once the foundation is in place, you can start building the wall. The materials you use will depend on your budget and the desired appearance of the wall. Concrete blocks, bricks, and stone are all common materials for perimeter walls.
5. Backfilling. 
   Once the wall is built, you need to backfill the trench. This will help to stabilize the foundation and prevent the wall from settling.
6. Finishing. 
   The final step is to finish the wall. This may involve painting, staining, or applying a textured finish.

Additional Tips for Constructing a Perimeter Wall:

• Hire a professional if you are not experienced in construction.
• Use high-quality materials to ensure the longevity of the wall.
• Make sure the wall is properly anchored to the ground to prevent it from tipping over.
• Inspect the wall regularly for damage and make repairs as needed.

Some of the Best Materials for Perimeter Walls:

• Concrete blocks: Concrete blocks are a durable and affordable option for perimeter walls. They are also relatively easy to work with.
• Bricks: Bricks are a more expensive option than concrete blocks, but they can provide a more attractive and long-lasting wall.
• Stone: Stone is a natural and durable material that can add beauty and character to a perimeter wall. However, it is also the most expensive option.
• Wood: Wood is a less durable option than concrete blocks, bricks, or stone, but it can be a good choice for a shorter wall or one that is not exposed to the elements.

The best type of perimeter wall for you will depend on your budget, desired appearance, and the specific needs of your property.
