Proving once more that caves indeed make an ideal living space, the semi-buried Photocatalytic Cave was designed as a private space for both retreat and social gatherings, in an existing 1960s hilltop residence by Mexican studio, Amezcua, just west of the city.

Mexico City’s Underground Residence: The Photocatalytic Cave

While historically characterized by its minimal ventilation, dim lighting, and high humidity due to the mass of earth and rock which insulate the space – the Photocatalytic Cave spans over 70 square meters with five distinct chambers comprising of a kitchen and bar, living room, dining area with a balcony, media area, wine storage and smoking area, plus a bathroom.

Shaping its epicenter, the cave was carved in limestone and fitted with Krion ^TM panels rich in photocatalytic properties which diffuse light and purify air, metal lintels and supporting columns through a sustainable K-Life technology process similar to those used in traditional coal mines. Utilizing anti-corrosive materials and air purifying features in the form of air injectors, dehumidifiers and heaters – the Amezcua team made issues of underground atmosphere and circulation a priority, cancelling probability of bacteria and fungi breeding, entirely.

Finished with wooden flooring, glossy surfaces and a combination of both light and dark cabinetry, the Photocatalytic Cave presents a sleek contrasting aesthetic – featuring contemporary furnishing such as curved leather sofas, wooden blocks and movable benches which fit the space like a puzzle piece despite the irregular dimensions.
