To obtain a good acoustic isolation in the theater, I used bricks to cover the concrete wall. Bricks are very responsive to sound absorption and reflection. I tried to create hollow and solid profiles with bricks. Some sound characters need reflection while others need absorption.
To achieve those hollow and solid profiles, I laid the bricks in a rotating pattern. The lower parts are laid straight to reflect sounds. Raising upwards the bricks are rotated 5 degrees to enable them to catch reflected and absorbed sounds in every direction. This way I could create not only a building but also a feeling and energy.
Apart from the material approach, I also approached it from the spirit of the space, the spirit of what would take place in the building. I think a theater can be established anywhere, even without a building. I proposed that the roof of the building be used as well as an open theater, thus we get two kinds of theater in one building, assince space actually exists just everywhere.

Teater Salihara will facilitate different art forms with various sonic and vocal explorations, therefore acoustics is an important issue. Acoustic planning deals with the hall acoustics and noise control to obtain a non-humming, clear and even sound, free of acoustic defects such as echo and auditory concentration. The theater is advantageously positioned, protected by other buildings from external noise.
A skylight would provide a good visual effect to Galeri Salihara as an exhibition space. To achieve thermal ventillation, air flow would enter and exit from the opening on the floor and upper walls. The ceiling is made from sound-absorbing materials to provide optimal acoustics.
The acoustics and lighting in the office building are is managed through the use of a sound-absorbing ceiling, and sufficient ventilation openings in the form of natural light windows. The acoustics, ventillation and lighting design do not follow any specific school of thought in design, but are based on the universal laws of physics. Natural lighting and good ventillation requires in-depth knowledge of the characteristicers of local materials and the humid tropical climate of Indonesia, where natural light is abundant.

Teater Salihara is a black-box theater, with flexible stage size and position, thus the equipment should be also flexible andy portable. The equipments should be able to be moved easily according to needs. An incredibly long 8,000 meters’ length of audio cable of 8,000 meters is needed. We avoid using wireless due to many constraints such as cellular phone interferences.
Beyond the technical issue of acoustics, I hope that Salihara will be more than a performance space, but also a place for study and human resource development. In that way the technicians would work proactively. The technicians should then be friendly, flexible, and able to grasp the artists’ aspirations, and have a willingness to develop themselves. The technicians should understand that despite their high technical abilities, eventually the ultimate show is the presentation of thewhole work of art itself.

Galeri Salihara is an oval-shaped building without ends and corners, enabling ample flexibility for the artists to display their works.
The important part of any gallery is the interior, as the works of art are to be displayed in it, and not the exterior building. The task of the building is only to provide an optimal space for works of art to be displayed in the best possible ways. Therefore light and ventilation are important. The interior should enjoy the maximum natural lighting. For those works of art that are sensitive to humidity and temperature, air conditioning is required. To provide comfort to the visitors, however, air conditioning is not necessary since there are the upper windows and the lower opening that allows the air to flow upward.
From outside, the curved surface renders the feeling of spaciousness of the areas between the gallery and two adjacent buildings. The spaciousness emphasizes the vitality of forming a space by expanding and narrowing, the oval shape is a strong visual feature that interacts with other square-shaped buildings. Thus the oval-shaped gallery creates a distinction as well as a dynamic integration.

The office building of Komunitas Salihara has the impression of floating in the air, thus it gives the feeling of lightness. The detached effect at the lower part is achieved using glass walls. A wall is installed at the front to absorb the noises from the street and to soften the sun-scorched west side. The south and north sides are left open through ventillation grids to let in the light and to substitute for the use of an air conditioner. Lamps are not needed during daytime as the building uses voids and a skylight system.
The office consists of four floors; the first two are for the curators and management. Beneath it is a library, a souvenir shop and toilets for the entire complex. The basement has an accommodation for artists. The access to the artists’ lodge is designed to allow the artists to walk in and out without being seen, while still enjoying the sunlight.
The library is not flat, it looks like a two-tiered level with a high ceiling to accommodate a mezzanine.
The whole complex consists of buildings each with their own characters and sense of spacing.

The people in the performing arts community, especially the lighting people, put much hope in the Salihara blackbox theater as most of the theater buildings in Jakarta have only a modest lighting system. Teater Salihara is a challenge to any Indonesian lighting designer. It can facilitate countless lighting design ideas, giving a maximum opportunity forof light point setting and light distribution.
