Inside a 95m² House Built Around a Sacred Void

Cajay House, designed by HW Studio, is a compact, 95-square-meter home completed in 2025 in Morelia, Mexico. At first glance, the house appears as a simple, almost hermetic box, quiet, solid, and largely closed to the surrounding city. But this restrained exterior conceals a very different interior experience. The central idea is not to make the house revolve around a physical object, but around an intentional void. An open stone garden that becomes the spatial and visual heart of the home. Once inside, the architecture begins to unfold around this garden. Inspired by the stone gardens of Kyoto temples, gray gravel and carefully positioned rocks create a calm, central landscape, while two wooden platforms float above it as places to pause and observe. Rather than functioning as decoration, the garden organizes the entire plan, with the main living spaces positioned around it. This creates a house where movement, views, and moments of stillness are all connected to the same central void. On one side, the double-height kitchen and dining area introduces vertical space into the compact floor plan, with a volume above designed to release smoke from a fire. Opposite it, the living room becomes a quieter space for contemplation, incorporating large stones into the interior landscape. Interestingly, these two areas are not connected by a conventional covered corridor. Moving between them means briefly stepping outside, so in the rain, you either get wet or wait for it to pass. It is a deliberate architectural choice that allows weather and nature to remain part of everyday life. Light is treated just as carefully as space. Traditional shoji doors made from rice paper act as a soft boundary between the interior and garden, filtering daylight and turning it into a subtle layer of shadow and atmosphere. The house uses very little glass, with only three small windows carefully positioned toward meaningful views. A mountain, a neighboring pine tree, and the tree planted at the center of the garden. Upstairs, the bedroom continues this restrained approach, with a single circular window framing the foliage below, creating a focused view rather than an expansive one. Even the entrance reinforces the house's philosophy. Instead of approaching by climbing upward, visitors descend into the home, following a staircase that reaches the firmer stone beneath the site, while also reducing unnecessary foundation work. The result is a compact residence with almost no unnecessary corridors, minimal openings, and a carefully controlled relationship between inside and outside. Keihai House shows how a small home can gain depth not through more rooms or larger windows, but through proportion, controlled light, landscape, and the deliberate use of empty space.
