3 Patios House is a modern two-story house located in Lomas de Chapultepec, Mexico, designed in 2018 by Once Once Arquitectura.


Casa 3 Patios was a project assignment for a Client to live the house with her teenage son. The program was to design a modern home that could be enjoyed in different ways in its interior and exterior spaces, to provide solutions for climatic comfort with passive and active energy systems, enhance state of the art sustainable solutions, and to be of commercially attractive if wanted to be sold.

We decided to approach the program creating a big central patio fully covered of a red Mexican granite stone, Porfido, mostly used as a floor finish in colonial plazas and courtyards to give authenticity and character. This patio was carefully thought to be closed with a glass facade on its south-east side and a skylight roof to receive the first sun rays and heat itself and the rest of the house by thermal mass heat radiation in winter season and to fully open and cool the house in summer time. This glass façade and skylight roof is accompanied with a steel lattice skin that has the quality of sliding with a rail system (in the skylight) and opening (in the façade) regulating the amount of sunlight and ventilation to come in. The guava tree in the center gives a sculptural mood, fruit, and in summer time, a nice shadowed area.

The house is entered by the Northeast corridor through a wild landscaped garden slowly discovering the house as you reach the Center Patio. Once inside a new experience unveils with an interior – exterior feeling. This cubic space of almost eight cubic meters is the heart of the house which has a multifunction quality working as a Hall, a dining-room, a meeting-room for work and for casual happenings, and even as a party or cocktail saloon. With its lattice pattern in the steel structure and the guava tree, every day there is a unique light and shadow experience on the red stone walls. This effect subtly reveals the time of the year and gives poetry to the house. From this patio, the rest of the house unveils: ground floor where all the social areas interconnect, basement where service, storage and machine room co-exist with its own patio, first floor hostages the private and more intimate areas, and second floor (roof-garden) where recreational activities are meant to happen with a Gym, pool, Jacuzzi, lounge and grill area.

The patio and the lattice are a celebration and reinterpretation of our heritage from Mediterranean an Arabic architecture using them as a the heart and skin of the house.
