With the growing needs of a large family living in the heart of the city, the owners envisioned a new home that could accommodate an expanding household while staying connected to the adjacent original residence. Situated on a compact 150-square-wah plot with a total usable area of approximately 1,000 square meters, the design challenge lay in maximizing functionality without compromising comfort or creating a sense of overcrowding. "Every space must offer quality living, privacy for all, and a welcoming environment for guests." This guiding principle shaped the layout of the home, which is divided into three zones across ascending levels to reflect their respective degrees of privacy. The ground floor houses service and utility areas, the second floor features semi-private guest and family spaces, and the third floor is reserved for workspaces and private living quarters. To optimize space and airflow, the design incorporates openings at the front and rear, leveraging the north-south orientation to catch breezes and avoid direct sunlight. A small pocket garden on the second floor adds a layer of privacy for the bedrooms, allowing for open views without the need for curtains while also softening daylight. The street-facing façade is defined by a solid, minimalist wall, ensuring privacy and simplicity. However, upon entering the main gate, visitors are greeted by a soaring double-height atrium that visually connects the ground floor with the second-floor guest area and extends toward a lush green living wall at the rear of the property. This design creates an illusion of expansive space, making the home feel larger than its compact plot suggests, while establishing an inviting atmosphere for entertaining. With its efficient layout, seamless flow, and thoughtful spatial design, this urban family home balances density with openness, addressing every need of its residents while remaining a welcoming and functional space for years to come.
