Construct Upper Retaining Wall

What happens here

As the 'grade kept on climbing' beyond the first tier, a second retaining wall, approximately 4 feet high as indicated by the narrator, was necessary. This wall creates an additional terraced area or further stabilizes the remaining slope above the main patio. Its construction follows similar principles to the first, including a solid foundation, proper drainage, and the use of robust interlocking blocks or poured concrete to manage the landscape transition. This wall is seen forming a small seating nook with a patio area at its base.

Goal: Build the second level of retaining walls for continued slope retention.
