1.5 million square feet / 135,000 square meters
This mixed-use development creates a vibrant destination in the heart of Jakarta using the Indonesian architectural principle of transparency between indoors and outdoors to establish a sense of place. The development features a 47-story International Grade-A office tower and an 18-story hotel tower, Four Seasons Hotel Jarkata. A three-level podium contains dining and event spaces and other hotel functions.
In the Indonesian architectural tradition, there is total transparency between indoor and outdoor space. Natural ventilation and natural light are also used extensively. In this architecture, semi-outdoor spaces — those that fall in between indoors and out — provide shade from sun and protection from rain. For the Four Seasons, such spaces occur at the ground level and throughout the entire height of the buildings. These include covered sidewalk cafes and other social spaces at the ground level and generous roof terraces at the banquet hall level and office floors.
The office tower massing steps back four times, creating a distinctive silhouette that is visible from both directions on Jalan Gatot Subroto, one of Jakarta’s main arteries. At the top of each step, there is a landscaped sky terrace. The tower façade is a double-glazed unitized curtain wall that features undulating anodized aluminum vertical sunshades arranged in a staggered pattern. Viewed diagonally, this arrangement gives the tower a distinguished wavy texture.
A rectangular extrusion in form, the hotel tower is set back on the site to provide distance from the busy main road. Vertical and horizontal sunshades animate the tower’s north and south facades. At the tower top, the façade is cut out to create a dining terrace, one of the development’s many outdoor spaces. Off the main lobby, the Palm Court, a triple-height glass atrium, is surrounded by ribbons of sunshades and a deep roof canopy.
Landscaping at the ground level continues the green spaces found throughout the towers and includes water elements that provide a cooling effect and covered informal gathering spaces set in lush gardens. In addition, rooftop landscaping on the hotel can be viewed by the office tower occupants.
