This pool is inside a private residence, located in a small town in Puglia (southern Italy), famous for its elite and refined tourism from all over Europe. The project involved the partial excavation and the creation of some special reinforced concrete structures to host the pool. The particularity of the project lies in the extreme customization of the finishing, simple but refined. The client requested an abundant use of the Trani stone, a carbonatic rock, typical of the region, which was used both inside and outside. The lighting is completely integrated into the furniture and the view towards the open side allows, during the summer season, to connect to the outdoor space continuing with the same flooring and the same formal internal logical path.
