01 Transformation of Transparency

The studio utilize AI, with platforms such as Midjourney and DALL-E, to generate feedback and inspiration during design iterations. Renderings and sections are generated using PromeAI, with prompt “Large public building, vernacular-modernism” and additional manual collages.

to provide transparency for the people to see

Constructing a new city amid the global environmental crisis, could be seen as a reckless decision. Indonesia is now in the process of relocating its capital city, built from scratch on top of an industrial forest. Yet, there are opportunities to make amend of the development and transforming the way we build buildings by designing carbon-negative buildings.

Using locally sourced timber from the former forest and developing transparent wood to complement glass will significantly reduce the carbon footprint of the construction.

Symbolized by the use of transparent woods that highlights potential of profound change within any entity, the transformation toward transparency is ideally extended to government practices, starting with the construction of legislative buildings in the new capital city.

FROM FOREST TO FOREST

As the development is located on top of industrial forest, utilizing the wood harvested from the forest could reduce a significant amount of carbon footprint for the construction.

Dukuh Atas Transit Hub

Dukuh Atas is an intersection area of by five different transportation modes in the heart of the city. The competition aimed to have a transit building for all passengers in the district. Several crucial issues in this project are connectivity between the building and all transportation nodes, sustainability, and redefine a new identity of a tropical high-rise building. Dukuh Atas Transit Hub is a small first step to regreenerate Jakarta. Type & Date

and creative Bandung music scene

During the 90s, Bandung was famous for its independent and underground music scene. The movement of the community happened in an organic way, on the outskirt area of the city, quite far from the center of the city. As the city grows and change in society throughout the digital era, the music community became spread and scattered.

Taking a site that is adjacent to the central train station, bus terminal, and proposed light rail transit system, the project is intended as a hub where people can see, hear, play, record and discuss anything about music. As the arena aimed to be an international-level venue that could showcase the local identitiy to the world, the building shape takes a modern translation of vernacular architecture of the region as the defining concept.

URBAN CONTEXT

The site is located at the intersection of different transportation modes: intercity train, commuter train, light rail transit and microbuses, 5km away from Bandung Airport.

Visitors and audiences from the city, out of town or even abroad could reach the venue easily. The more visitors from various background come, the more significant and diverse the music could be incubated.

STORY: PROGRAM AND SEQUENCE

With the vision to be a national music incubator space, the programs in the building aim to tempt visitors to be involved in the music world. “Space-event-movement” is the main concept of the sequence, to connect events called music cycle to fill the space. Spaces resulted by movements towards every events are intended to turn visitors into music lovers and then musicians.

The listen zone is where visitors will listen to music played by music communities and record stores. Curiosity will lead them to try to play musical instrument in the stores and rehearsal studios in the play zone. The recording studio in the record zone provide chances to record the music composition, before performing in the perform zone: restaurants, cafes and bars and, ultimately, the main concert hall.

Wisma Sudirman in the middle of Sudirman Street, the busiest district in Jakarta

Yes, another mixed-use development in Jakarta. Yes, 250 meter high rental office tower and super expensive apartment building again. Yes, one more shopping mall and exclusivelyupgraded hawker center. Another compact, high traffic and high occupancy development at the already busy business district in the capital city.

Yet, a development in the city with a welcoming entrance plaza at the front of the development is still an oasis in the concrete jungle of Jakarta. No other retail complex directly connected to the Mass Rapit Trasportation station at the basement. No other office and apartment tower with open terraces of this quantity. Wisma Sudirman is a kind of its own. A unique mixed-use development with an engaging public plaza and underground subway interconnection at the heart of the busiest district in Jakarta.

New residential design offers more typical and symmetrical unit layouts, an evaluation from the client as the previous design was hard to sell due to too many unit type variations, too much inefficient space, and full-length perimeter balconies.

Duplex Residential Floor Plan

The new building design needs to provide parking at the podium levels. This offers a chance to introduce a unique residential concept: duplex units with private parking accessible from the back door. There are three types of duplex units available.
