Located within an urban residential complex in a suburban area, Casa A occupies a 700-square-meter corner plot with a total built area of 956 square meters. Positioned at a junction adjacent to a public green space, the site offers visual openness and environmental potential within a dense housing context.
The design was shaped by three key triggers. The first emerged from the client’s desire for compact living. While initially considering apartment living, spatial limitations—particularly for an automotive hobby—prompted a reconsideration. The second trigger came from a story shared by the client: a man living inside a dark cave surrounded by lush greenery, where nature and light become powerful experiences from within. The third influence was drawn from the client’s previous home, where a single shared space became the emotional center of family life, allowing individual activities to unfold together. Preserving this sense of intimacy became a central design objective.
Casa A is conceived as a “landed apartment,” redefining conventional residential zoning. The ground floor is fully dedicated to the client’s automotive interests and treated as an extension of the landscape rather than a traditional living floor. Daily living spaces begin on the second and third levels, creating a clear transition between hobby, landscape, and family life.
This transition is reinforced through a reinterpretation of the entrance sequence. Instead of a direct threshold, the house introduces a layered arrival. From the foyer, occupants move through a semi-outdoor stair conceived as a vertical landscape. Carefully calibrated proportions and light create a cave-like spatial experience, reinforcing the narrative of moving through nature before reaching the living spaces.
The two-story living volume accommodates everyday family activities. The second floor is organized as a free-flowing open plan comprising kitchen, dining, living, and family areas. Three bedroom volumes occupy the third floor, separated by voids that maintain visual connections and strengthen family interaction across levels.
Facing west toward the adjacent green space, the house receives strong afternoon sunlight. Existing trees were preserved and complemented by additional planting to soften daylight and improve microclimate conditions. An expanded metal façade provides shading while visually blurring the boundary between interior and exterior. Vertical landscape elements within the courtyard further enhance the sensation of being immersed in nature.
Casa A reflects Wahana Architects’ approach to residential design, where spatial storytelling, environmental sensitivity, and human intimacy are thoughtfully interwoven.
