At first glance, building a pool right beside another body of water seems a little redundant. After all, why would someone choose to swim in a pool when they have a river or ocean to enjoy? However, for people with limited mobility and younger more inexperienced swimmers, natural bodies of water can prove both daunting and dangerous. Pools not only provide a controlled, secure space for them to enjoy aquatic activities, they also provide a connection with the surrounding landscape.

Due to its ability to mold and create different shapes, concrete is one of architecture's most popular materials.

Founded in 1541 by the Spanish conquistador Pedro de Valdivia on indigenous settlements in the valley of the Mapocho River, Santiago is the capital and most populated city of Chile. This South American city is enframed by the Andes Mountains to the east and the Chilean Coast Range to the west, in addition to 26 island hills (cerros islas) scattered throughout the city. Some of these island hills have been converted into urban parks, such as Santa Lucía and San Cristóbal, while Chena, Calán, and Renca are in the process of expansion.
