ASEAN Headquarters
The ASEAN 'Headquarters, formerly known as the ASEAN Secretariat Building', serves as the headquarters of the Association of Southeast Asian Nations, located on Jalan Sisingamangaraja in Kebayoran Baru, South Jakarta, Indonesia. It houses the ASEAN Secretariat, the ASEAN Inter-Parliamentary Assembly, and the organization's permanent administrative offices. It functions as the central venue for regional meetings and diplomatic coordination among the bloc's eleven member states. The complex consists of the original 1981 Secretariat Building, designed by Indonesian architect Soejoedi Wiroatmodjo, and the 2019 twin-tower expansion, designed by Bentara Indonesia Arsitek. The original structure, inaugurated by President Soeharto, is an eight-storey modernist edifice whose terraced form was inspired by the region's terraced rice paddies.
In 2019, the Secretariat complex was expanded with the addition of twin 16-storey towers featuring a record-setting 41-metre column-free skybridge, which greatly expanded the organization's capacity to host meetings and support its growing administrative functions. The Secretariat building plays a central role in ASEAN's operations, diplomacy, and community-building efforts, and has hosted numerous high-level events since its inauguration.
History
Planning
Site
The idea of establishing a permanent ASEAN Secretariat emerged as ASEAN's activities expanded in the 1970s. At the first ASEAN Summit in Bali, the ASEAN Foreign Ministers agreed to create a permanent ASEAN Secretariat to improve coordination, and crucially decided that its seat would be in Jakarta, Indonesia. Notably, the selection of Jakarta was preceded by debate. Indonesia had early on offered Jakarta as the Secretariat's home: by 3 May 1974, Indonesian Foreign Minister Adam Malik announced that a plot of land in Kebayoran Baru was set aside for an ASEAN Secretariat headquarters, an area historically known as "CSW", a former Dutch industrial yard turned into a government district.However, the Philippines soon challenged the plan. President Ferdinand Marcos directly proposed Manila as an alternate site, even earmarking a location on Roxas Boulevard. Adding that the Philippines were fully committed to the funding of the ASEAN Secretariat for the course of the first two years, going as far as formulating a government budget plan for the building. Deadlock on the proposed site between the two nations came to a head at an ASEAN Foreign Ministers’ Meeting in Jakarta at the Borobudur Hotel in May 1974, where the members discussed the competing offers. However, neither nations nor the foreign ministers had led to consensus.
Consensus was finally reached at the First ASEAN Summit on 23 February 1976 after ASEAN's foreign ministers held preference towards Jakarta as the centre for ASEAN's Secretariat. ASEAN held preference towards Indonesia as the host, given its size, central geography among the original members, and held diplomatic sway and stature in Southeast Asia. Its capital Jakarta was also seen as a neutral, centrally located city with stability and adequate facilities to serve as ASEAN's diplomatic hub. With so, the Roxas Boulevard proposal was eventually rescinded, and the 1976 Agreement on the Establishment of the ASEAN Secretariat, signed by ASEAN's founding members, formally codified Jakarta as the host city.
Design
In July 1976, the Indonesian government announced the initial construction phase, with Rp 2.8 billion in funding from the state budget. After securing the bid for the secretariat, the Indonesian government entrusted the architectural design of the ASEAN Secretariat building to Soejoedi Wiroatmodjo. Soejoedi was a prominent and renowned figure in modernist Indonesian architecture, having been the chief architect for national projects in Jakarta. With a portfolio of designing several important government buildings such as the Conefo Organization Headquarters and multiple government ministry towers. His firm, Gubahlaras, was commissioned to design the ASEAN Secretariat headquarters. Likely chosen due to his reputation for blending modern design with national/regional identity; described as within a conviction of "universal humanity and the spirit of contemporariness". Planning and design work began in the mid-1970sThe design by Soejoedi held a blend of modernist form with Southeast Asian cultural inspiration. Soejoedi eschewed overt traditional motifs; instead, he sought to express ASEAN's identity through his personal philosophy of spatial form and symbolism. Under his design philosophy, Soejoedi told Konstruksi Magazine in 1980, that his design for the building intends to embody the spirit of openness and reflected the nature of cooperation among Southeast Asian countries. The building stands 8–9 stories tall with a broad, horizontal. Notably, its tiered, stepped silhouette was inspired by the terraced rice paddies common across Southeast Asia. Gubahlaras architects explicitly likened the building's layered profile to "sawah terasering" as an homage to the region's agricultural heritage and a visual metaphor for ASEAN's cooperative growth. This terraced form under horizontal bands or setbacks as the building rises, was intended to reflect the agrarian foundations of ASEAN economies at the time and to symbolize growth and abundance.
Construction began in April 1978, work started on the structure using some of the same construction machinery that had been used for the Hotel Indonesia by the state-owned firm PT Pembangunan Perumahan. In November 1979, three thieves stole 10 typewriters, four calculators, a clock, and a radio from the site; they were arrested a month later, after some items had already been resold. In terms of materials and features, the original building was constructed with practicality and regional aesthetics in mind. The exterior was clad in ceramic tiles instead of paint, a choice made for durability and ease of maintenance in Jakarta's tropical climate. The windows used brown-tinted glass imported from Japan, giving the façade a distinctive bronze reflective hue while reducing glare and heat from the sun. The structure's footprint provided about 10,000 square meters of floor space across its nine levels, including a large main hall intended for meetings. Internally, the design was functional and modern by early 1980s standards, with simple geometric forms and open-plan office areas based on Soejoedi's philosophy of integrating form with function. The building's site orientation was carefully considered to harmonize with its surroundings.
Opening
On 9 May 1981, Indonesia's President Suharto officially inaugurated the ASEAN Secretariat Building, in a ceremony attended by the then Foreign Ministers of ASEAN member states and the original ASEAN "Big Five" founders. Prior to the inauguration, ASEAN Secretariat staff were already moved into the new building after being housed in temporary offices at Indonesia's Foreign Affairs Ministry compound on Jalan Taman Pejambon while ground preparations and design finalization for the new building continue. At the inauguration, President Suharto remarked that the ASEAN Secretariat building stood as "the unwavering determination of the 250 million people of the five ASEAN member countries to unite." The opening of the new ASEC headquarters was followed by the celebration of ASEAN's 52nd anniversary, which included a series of community-based commemoration activities. The festival intended to show ASEAN's inclusivity and youthfulness.In a joint communiqué issued in Manila in June 1981, the foreign ministers of ASEAN states declared that the new headquarters marked a new chapter for ASEAN cooperation. The cost overrun for the ASEAN Secretariat totalled up to Rp 5 billion rupiah. The building quickly became the venue for significant ASEAN events. Its first major outing was for Brunei Darussalam's accession to become ASEAN's sixth member in January 1984, signed and deposited in the Secretariat in Jakarta.
Proposals for expansion
Initially, the headquarters in Jakarta served the modest administrative needs of its Secretariat. However, as ASEAN expanded in complexity and membership in the decades after the ASEAN Charter and especially leading up to the launch of the ASEAN Community in 2015, the original building became increasingly inadequate for the organization's much larger diplomatic, administrative, and representational functions. The expansion discourse emerged around 2012, when the Indonesian and ASEAN governments discussed utilizing the former unused South Jakarta Mayor's office for the use of the secretariat. Governor of Jakarta, Joko Widodo, was involved in the beginning rehabilitation negotiations. The land grant was approved in 2014 during the governorship of Basuki Tjahaja Purnama, known colloquially as Ahok. At the time of transfer, a debate emerged over whether the ASEAN Secretariat should renovate the existing South Jakarta mayoral building or construct a new facility on the site. Ahok, a strong proponent of expanding the organization's capacity in Jakarta, advocated and proposed the building of a new structure to meet ASEAN's long-term needs, going as far as to send an assessment team to evaluate the building's feasibility for use under minimal renovations or the necessity for rebuilding.By 2015, the aging secretariat was in need for a new, larger, modern, and symbolic headquarters that could accommodate the permanent missions, meeting facilities, and staff that accompanied ASEAN's deeper institutionalization. This context led to an open architectural design competition in 2015, coordinated with professional bodies such as the Indonesian Institute of Architects, drawing entries proposing a landmark complex for the secretariat, with 80 competing entries submitted to the competition. The competition was organized with the Indonesian Institute of Architects Jakarta, with Ministry of Foreign Affairs and ASEAN involvement; IAI channels also posted the jurying and winners. The criteria set for the building were the creation of a landmark building that Hengky Pramudya represents the spirit of the ASEAN organisation in the global community. Another important design criterion was energy-efficiency, maximal utilisation of natural lighting and ventilation. The area sighted for the proposed building site was identified as being in the Jalan Trunojoyo area, on a former site of the South Jakarta mayor's office.
On 16 November, the winning proposal was eventually announced by the IAI, with and team won First Prize in the 2015 design competition for the new ASEAN Secretariat. The award was announced on 23 December 2015. The winners were then gifted a sum of Rp. 500 million on behalf of the ASEAN Organization.
On the occasion of the 49th anniversary of the ASEAN Declaration on 8 August 2016, Indonesian Foreign Minister Retno Marsudi publicly announced plans to expand the ASEAN Secretariat. Initially, the project envisioned a 17-storey building with two semi-basement levels, with construction scheduled to begin in early 2017 and to be completed by the end of 2018. The winning competition design was subsequently developed into the twin-tower ASEAN Secretariat complex.
