Premier Office, an office building located on a quiet street in Ho Chi Minh City, Vietnam, is covered by brick walls with a concrete structure. The functional areas are divided by a continuous vertical void in the centre, which helps natural light and airflow going throughout the building.

One side of the central void is the office space, with two facades opening to catch the sunlight and wind. The other side accommodates the restroom, storage, elevator, and stairs. The two blocks are connected by corridors spanning the void. By connecting the void between the corridors and empty spaces, both vertically and horizontally, the building can create moving light areas and space displacement during the day.
A double-layer with a unique “brick curtain” outside, and aluminum sliding glass doors inside fills the spaces with light and ventilation. The perforated brick wall structure rotates at a 45-degree angle to create a buffer layer that reduces the impact of sunlight and creates moving shadows. The buffer layer, with trees interweaving, contributes to purifying the air and stopping direct sunlight from entering the workspace. With the use of clay solid brick, steel, concrete, a perforated brick shell, rotated wall, and the gaps, the office blends into the neighborhood.
