National Spirit

http://www.srssa.com/Signature_Tower/spirit.html

Signature Tower Jakarta celebrates the Indonesian spirit through the reinforcement of the date of the National Day of Independence, 17 August 1945, viewed on each façade of the tower. Visible during the day through the use of highly polished stainless-steel, 17 leaves grow and blossom upward through the shaft of the tower.

At the crown, these 17 leaves are bound together by 8 louver grill elements, culminating to embrace a single 45 meter tall spire: the 17th day of the 8th month in the 45th year.Central to the four building elevations of the crown, these elements in turn are supported by 5 crystalline glass buds – accentuating the five principals of Pancasila – rising to support a single central spire – the united Indonesian people. Hence the budding flower (Pancasila) spreading from all corners of the tower, spreading to all corners of Indonesia.

In the evening on national holidays, we envision the 17 leaves would be outlined with white LED lights, the supporting 8 louver grills up-lit in red light, the center glass buds back-lit in white light, and central spire illuminated with 45 red and white LED bands. During non-holidays, the lighting would be able to be changed to suit the particular occasion.

THE TOWER

The 111-story tower rises 638m above the ground plane to the top of the spire. The highest floor sits approximately 534.45m above the street entry. While a simple 60m by 60m square form dominates the planning of the tower, achieving an elegant aspect ratio of approximately 9:1, the tower facade steps to accentuate the different uses within the complex; i.e.: retail and convention at the base, office use through the shaft, and hotel use at the crown.

The regular form of the tower, with notched corners, provides a straight forward and efficient planning platform for tenants to utilize, including an average 13.5m clear depth from the core wall to the exterior curtain wall and opportunities for multiple corner offices on each level.

The structural approach utilizes a super-column and out-rigger arrangement, surrounding an inner core wall. It is anticipated the structural system will be based on composite steel and concrete.

THE PODIUM

Separate monumental lobbies, in scale with the overall tower development, welcome Hotel Guests and Office Tenants at Ground Level. An exclusive banking hall fronts the main access to the office tower lifts, as well as act as a gateway into the retail portion of the podium. Access to the Observatory is via an experiential queuing and ticketing space at the Lower Ground Level.

Allowing it to operate at times when the retail mall is closed, segregated access is provided to an entertainment / restaurant area that is located on the roof of the podium, above the 5,000 square meter Function Space. An independent entrance allows guests to arrive at the Conference Center via dedicated lifts or escalators that travel within the perimeter of the podium glass wall, separated from the retail mall customers.

Exclusive retail space is organized around a larger, 4-story atrium, with expansion planning incorporated to accommodate future development of Lot 8.
