Casa Plan de Barrancas is a minimalist residence located in Mexico City, Mexico, designed by PPAA. The project stages a deliberate tension between dissolution and enclosure, between a ground plane that dematerializes into its setting and an upper volume that asserts itself with quiet solidity. This duality drives nearly every decision in the house, from material selection to site response, and positions the work within a lineage of Mexican modernism that has long wrestled with how architecture should meet both the street and the garden.
The western neighborhoods of Mexico City carry a particular relationship to landscape, where mature trees and walled gardens have historically produced a dense, layered urban fabric. PPAA approaches this context by inverting the expected logic of the urban house. Rather than presenting a defensive facade to the street, the ground floor behaves more as a landscape intervention than as architecture. A large planter integrated into the volume extends the interior vegetation outward, while a reflective material clads the base and absorbs the surrounding greenery into its surface. The effect recalls the mirrored interventions of Dan Graham or Anish Kapoor’s urban pieces, though deployed here toward a domestic end. Entry points and the garage disappear into this reflective plane, leaving the upper mass appearing to hover above a continuous, almost immaterial field of foliage.
Above this dissolving base sits a contained volume housing the private program of bedrooms and studies. Its matte, opaque skin carries a vertical striation worked into the plaster finish, a texture that reads differently as light moves across it through the day. This is a quiet reference to the tradition of board-formed concrete and combed stucco in mid-century Mexican work, though PPAA handles it with a restraint closer to the sober geometries of Alberto Kalach or the later work of Teodoro González de León. Openings in this upper mass are selective and deliberate, calibrated to frame specific views rather than to admit light indiscriminately.
The volume is shifted on its base in direct response to a jacaranda tree along the street, and this displacement generates a terrace that reads as a carved absence rather than an added amenity. The move reflects PPAA’s ongoing interest in the defined void, the idea that unbuilt space carries the same design weight as built mass. This is a position with deep roots in Japanese spatial thinking, though it also aligns with Luis Barragán’s understanding of the patio as a constructed emptiness. Architecture becomes the simultaneous shaping of matter and space.
