Organized around a generous open-air patio that provides shelter, privacy, and light, the design of Casa Ithualli is about connecting interior and exterior, facilitating direct access to open spaces, emphasizing natural light, and using ordinary materials in novel ways. A base of exposed concrete provides privacy on the ground floor, while a latticework of staggered metal tubes on the upper level filters the light and views. Inside, the main living spaces open out to the central patio via a double-height glass curtainwall.
The residence was constructed in six months as the grand prize for the Sorteos Tec lottery, which has provided scholarships to over half of all students at the Tecnológico de Monterrey over the last 70 years. In recent years, the lottery has sought out internationally-recognized architects to provide exceptional designs in support of the lottery's mission to transform Mexico through education.
