By subverting the conventional design of an ancestral shrine, a four-person household that has been lived in for over 20 years is transformed into a "dojo for life." Taking advantage of the multi-level layout, the design establishes a settlement model where a large house encloses smaller houses," redefining the role of common spaces to function as courtyards akin to traditional homes. These shared spaces link three small suites, fostering a renewed perspective on intergenerational cohabitation. Rooted in shared faith, the design draws from Dunhuang Caves and Tibetan prayer wheels, using curves, concaves, and openwork to shape a spiritual spatial narrative. A stone cabinet wall in the foyer guides movement with shifting light and shadow, creating a tunnel-like transition from darkness to lightechoing the path of self-cultivation. Reflecting a shift toward a lighter, plant-based diet, the once-enclosed kitchen is now open, connecting with the living room to form a communal courtyard-like space. This central area links the hallway and staircase to three suites, balancing intergenerational privacy with opportunities for connection and shared experience. With a subtle approach, emotionally significant objects and spaces are preserved and refined. Elements like living room calligraphy, a curvy-railed bench, and the staircase are simplifiedslender metal supports and restored wood finishes enhance clarity while honoring memory. The shrine, often distinct from residential life, is redefined as a sacred, multi-level space facing an open window. Its inward curve creates solemnity while blending into the home's horizontal flow. Inspired by gallery aesthetics, intentional emptiness and framed views elevate its spirituality. As a living dojo, it integrates ritual and daily life, offering a new model for sacred space at home. Integrating unused spaces, the "large house enclosing small houses" arrangement creates a new living relationship between two generations.
