Originally serving as a restaurant and wedding banquet hall, this building was extensively repurposed and transformed into the corporate headquarters for a construction company to accommodate the owner’s expanding business operations. The spatial program is meticulously organized across three levels: the ground floor functions as a reception center; the second floor integrates a client customization zone, fitness facilities, and meeting rooms; and the third floor is dedicated exclusively to the company’s administrative and management operations.
The existing structure presented significant architectural challenges. Windows were located exclusively on the eastern facade, and with ceiling heights of only 3.2 meters—with the exception of the ground floor which reaches nearly 4 meters—the interior environment originally suffered from poor natural lighting and stagnant ventilation.
To address these deficiencies, we introduced four voids through the second and third-floor slabs, establishing a dominant visual and functional axis for the entire building. These voids act as light wells, drawing natural sunlight from the third-floor down through the core of the building to the first and second levels. This strategic intervention not only illuminates the workspace but also effectively alleviates the spatial pressure caused by the restrictive ceiling heights, creating a sense of openness.
On the second floor, we took the bold step of removing the original glass curtain wall and reducing the interior floor area to make room for a lush, verdant balcony and terrace along the primary facade. This provides staff with a serene, green retreat for dining and relaxation during breaks.
Furthermore, this outdoor space was designed to harmonize with the third-floor terrace of the adjacent headquarters building belonging to the same corporate group. Together, these terraces form a continuous chain of "floating green islands" in a vertical landscape. This design choice not only fosters a sense of unity between the two corporate buildings but also enriches the urban fabric, adding a much-needed layer of rhythmic greenery to the city skyline.
