A high-level boundaryless swimming pool plan typically refers to a design for a swimming pool that does not have physical boundaries, such as walls or fences, allowing users to swim freely across an open space. This type of pool design is often seen in luxury hotels, resorts, or upscale residential complexes. It requires careful planning to ensure safety and compliance with local building codes. The design might include features like overflow edges, vanishing edge effects, and integrated landscaping to enhance the aesthetic appeal and functionality of the space.
