The development consists of two towers rising m to the north and m to the south, linked together at the feet by a m podium housing the main lobbies, a conference center, cafeteria, and exhibition space. The volume and height of the HQ was predetermined by the urban masterplan, leaving BIG with façade design. BIG envisioned an undulating façade &#; like the structure of a palm leaf or the folded screen of a lamp.

The base of the building utilizes the maximum area of the site, housing TV studios and , sq ft of retail space over multiple levels. The lobby is connected to the WTC transit hub, providing direct access to subway lines and PATH trains. A public plaza at the foot of the building and access to shopping and restaurants in the adjacent transportation hub and concourses will ensure life and activity in and around the new World Trade Center.

The simple manipulation of the archetypical space-defining garden wall creates a presence in the Park that changes as you move around it and through it. The north-south elevation of the Pavilion is a perfect rectangle. The east-west elevation is an undulating sculptural silhouette. Towards the east-west, the Pavilion is completely opaque and material. Towards the north-south, it is entirely transparent and practically immaterial. As a result, presence becomes absence, orthogonal becomes curvilinear, structure becomes gesture and box becomes blob.

Every element is designed to guarantee excellent light quality with high efficiency and low energy consumption. Long running times unplugged go hand- in-hand with rapid recharging times. The soft, diffused light emission can be adjusted to different brightness settings to create different ambiances. It is perfect for everyday lighting scenarios in personal spaces, but also for more social moments.

As a projection of a geometrically perfect circle on to the steep slope, the new gallery is conceived as a courtyard building that combines a pure geometrical layout with a sensitive adaption to the landscape. The three‐dimensional imprint of the landscape creates a protective ring around the museum’s focal point, the sculpture garden where visitors, personnel, exhibition merge with culture and nature, inside and outside.
