A new exhibition presents low-cost solutions for Jakarta’s housing problems.

Celebrating and reviewing Indonesia's architectural developments, the Indonesian Institute of Architects (IAI) held IAI Design Week last last October. Scattered across several venues in Jakarta, the festival included seminars, workshops, exhibitions and film screenings.

One of the most talked-about exhibitions was Rusunawa Jatinegara at the National Museum of Indonesia, which showcased the winners of a low-cost vertical housing competition held by the IAI in cooperation with the Ministry of Public Works. Local architects competed to design the best vertical housing solution for a government-owned site in a riverside residential area of Jatinegara Barat in East Jakarta. The competition brief called for two towers of residential blocks, with a maximum of 16 floors and 280 units per tower. Though just 30 square meters in size, each unit was required to have two bedrooms, a bathroom, a kitchen, a living room and an area for drying clothes.

Judging the entries by their buildability, creativity, and social and environmental sustainability, the competition crowned the top three entries last July. The second runner up, designed by a team of architects led by Toton Suhartanto, saw single-loaded corridors arranged in a triangular plan. Spiraling continuously through the 16 floors, a wide ramp serves as each tower's main point of circulation, which is meant to encourage more social interaction between floors. The first runner up design, by architects Irina Kencana Sari and Sandhi Yudha, featured a pair of elegantly curved towers that are linked by bridges on every third floor. Also designed with single-loaded corridors, the two towers opened to a mutual courtyard garden, providing their residents with green open space.

In contrast to the runners-up, the first place winner opted for a tricky double-loaded formation, with apartments on both sides of the corridors. Designed by architects Anindhita Sunartio, Ferdy Apriady, Rikko Putrawan, Russelin Edhyati and Tirza Wijaya, the units are arranged in a staggered plan, exposing more sides of each unit to natural light and air. The design was praised for its details, such as a communal void to induce both a passive cooling effect and social interaction between floors; a merchant's window (an aperture facing the corridor in each unit that is intended to encourage entrepreneurship), a zero-runoff rainwater harvesting system; and a bridge connecting the vertical housing to the sprawling kampongs on the other side of the Ciliwung River. With the operational costs of the government-run housing in mind, the east and west faces of the tower can be used as space for advertising. This winning concept is currently being refined for construction.
