To justify the house's existence, HW Studio imagined Casa JA from the beginning asa discreet horizontal line, highlighting the sky and mountains in its background, with the sun's rays flowing between them. The main interior of the house was carefully hidden by the design studio from passers-by on the street. The studio wanted the house to be intimate and quiet, just to hint at its presence.

The black stone interior falsely accentuates the cover, highlighting the sun, sky and mountains on the horizon. Throughout the design process, the magical sunset felt from its location was very important to the design. It is hoped that these Spaces will be influenced by the beauty of this light, which will produce a special charm.

The house is divided into three volumes at different levels, connected by wide covered and uncovered stairs, forming a continuous and flowing space. Gardens, terraces and plazas organize the rest of the project, providing a sense of introspection, domestication and silent nature, an intimacy and reminiscence that fills the space, reminiscent of the prehistoric and colonial architecture of some towns in the State of Michoacan.
