Sequest Building

The Signature Tower sets a new benchmark for Indonesia's rapidly developing capital through its meticulous urban design, clear skyline composition, and commitment to sustainability. Robert Whitlock, Design Director at KPF and FAIA fellow, says: The design of the Signature Tower began with simple linear forms that we bundled together and adjusted in height to create landscape terraces. We used the banyan tree as a metaphor for the tower, hoping it would grow organically like a series of finely detailed elements at different scales. The tower is composed of four bundled and curved super-tubes that are offset and nested within one another. This design not only creates visual interest but also generates a series of floor plates that produce a unique office form while providing better structural stability for a building in this active seismic zone. At the top of the tower, the super-tubes begin to vary in height, each forming large sky gardens that overlook the entire city, while platforms extend outward to support larger office floor plates and increase pedestrian permeability across the site. The architects carefully analyzed the surrounding context, site constraints, and researched ways to optimize energy efficiency and performance, and these explorations drove the building's design strategy. Jakarta's pedestrian connectivity is limited by traffic and parking areas, and compared to standardized planning models, this tower emphasizes the importance of ground-level pedestrian experience. By moving ground-level vehicular traffic underground and elevating the building, the design creates a more walkable, humane urban environment at the base.
