Quick answer：

An enclosed swimming pool in a villa typically refers to a private swimming pool that is surrounded by a structure, such as a deck or a fence, to create a semi-private or private space. This feature is often found in luxury homes and upscale residential areas. Enclosed pools can offer additional privacy, protection from debris, and temperature control through the use of a roof or greenhouse-like structure. They can also be designed with various features like waterfalls, jets, or lighting for aesthetic appeal.
