A borderless swimming pool is an architectural design that creates the illusion of a pool extending indefinitely by using water features and landscaping to blend the pool with its surrounding environment. These pools are often designed with vanishing edge techniques, where the water appears to drop off into nothingness, creating a seamless transition between the water's surface and the surrounding area. They are popular in luxury resorts and high-end residential projects for their aesthetic appeal and the sense of tranquility they offer.
