Project for a Hostel La Isla Holbox. It is a small island located north of the Yucatan Peninsula in Mexico. It is accessed through the town of Chiquila located in the extreme north of Quintana Roo, approximately 2.5 hours by car north of Cancun. The BEACH HOSTEL UNIT is presented as a real and different option for all those who want to be in balance with the natural ecosystem but with the comfort of modern life. For the conception of the project, it is essential to understand who it is aimed at, which is why it must have Smart House characteristics, which satisfy any basic activity of young travelers. The project was carried out within the framework of an AG360 International Ideas Competition, which was suspended when it had almost concluded, so I decided to continue it as an object of research.
