The cost of constructing a dry landscape, also known as a 'kare-sansui' or 'dry rock garden,' can vary widely depending on factors such as the scale of the project, the quality of materials used, and location. Generally, it can range from a few hundred to a few thousand dollars per square meter. The design complexity, inclusion of additional elements like stepping stones, and whether it is a custom or pre-designed landscape also play significant roles in determining the final cost.
