Casa La Joya, located in the natural surroundings of Valle de Bravo, Estado de México, stands out for its harmonious integration with the landscape. Surrounded by oak and pine forests and offering views of the lake, the house emerges as a retreat that respects and celebrates its context. Built between 2015 and 2018, the design faced challenges such as a narrow, steeply sloped terrain with dense vegetation. To preserve the ecosystem, the house was elevated on columns, allowing trees and natural water flow to remain undisturbed. The region’s temperate and humid climate inspired passive strategies that maximize cross ventilation and thermal comfort. The structure adapts to the site, minimizing environmental impact and fostering a close connection to nature. Terraces and patios weave through the vegetation, offering lake views and enveloping the home in its natural surroundings, while the interiors balance open spaces with private, intimate areas. Inspired by the forest, the architecture uses local materials such as volcanic stone, certified wood, and red brick, combined with modern technologies like double-glazed windows and rainwater harvesting systems. Distributed over three levels, Casa La Joya includes social areas with a terrace, swimming pool, and jacuzzi on the ground floor; panoramic-view bedrooms on the upper level; and service areas in the basement. The design promotes well-being, offering unique experiences such as enjoying the landscape from the terrace or retreating into an inner courtyard. With sustainable strategies including wastewater reuse and high-efficiency thermal materials, Casa La Joya reflects a strong commitment to the environment. Its innovative and responsible approach positions it as a model of sustainable architecture in harmony with its natural setting.
