Cohuatichan is a 715 m2 weekend residence located in the Mexican mountains of Puebla. Attached to the edge of a cliff overlooking a 100ha site, the house has stunning views of a waterfall and the surrounding tropical cloud mountain forest. The exuberant context guided the design of this holiday residence extension. The integration of both interior and exterior programs was achieved through the use of a large sliding curtain wall on both levels intended to remain open while the house is in use. This allows the house to open up to the unique landscape, while also connecting the adjacent infinity swimming pool with the public living area on the lower level, and the master bedroom with an open hot tub, bathroom and terrace on the upper level. The house’s aesthetics and materials were kept light and clean in contrast to the breathtaking surroundings in order to foster a unique experience of outdoor living while being under the comfort of a contemporary structure.
