Departing from conventional design norms, the staircase was reimagined within the existing structure using unique methods to transform its shape, allowing light to penetrate and dispel the previously dark areas. In addition to this, various intimate spaces have been thoughtfully designed throughout the home, providing each family member with their own personal retreat beyond their bedrooms—such as cozy nooks by the balcony, window seats, and spaces beneath the stairs. These individual spaces offer places for relaxation while communal areas, like the living room and dual-facing sofa zones, serve as gathering points that bring the family together. In material selection, reflecting the client’s preference for understated elegance, opted for minimalist, natural materials. For the study, natural Fukien cypress was chosen for the ceiling, allowing the homeowner to enjoy its soothing natural aroma that helps alleviate daily work stress. On the second floor, sliding doors are combined with floor-to-ceiling windows to create a visual connection between the indoors and the balcony, enhancing the sense of openness. Additionally, the dining area features blue Fenix panels, known for their low reflectivity, ultra-matte finish, fingerprint resistance, and soft, comfortable texture. One of the primary challenges was introducing natural light into the space by removing existing glass windows. Due to the building's height, this was a complex task requiring careful planning and execution. To reinforce the structural integrity of the walls, the design team leveraged its professional design expertise, adding safety enhancements to the old building. The structural columns in the first-floor living room not only support the floor above but also, through thoughtful lighting design, symbolize the family’s emotional pillars. This integration of structural and aesthetic elements has elevated the living environment, creating a cozy and spacious ideal home the homeowners envisioned.
