A rendering of a guesthouse with an infinity pool

Quick answer：

An infinity pool is a type of pool that extends over the edge of a property, creating the illusion of water merging with the horizon. It is often used in guesthouses, hotels, and luxury homes for aesthetic appeal and to enhance the sense of relaxation. Renderings are detailed two-dimensional drawings or images that illustrate the design or appearance of a building or structure before it is constructed.
