The design of a villa's overhead swimming pool involves creating an architectural feature that integrates a swimming pool with the structure of a house. This design must consider structural integrity, aesthetics, safety, and privacy. It often includes a deck or platform above the pool, with considerations for the pool's depth, shape, materials, and how it connects to the home. Additionally, the design must address factors like lighting, landscaping, and water features for a harmonious integration with the surrounding environment.
