Türk Telekom Opera Hall is a performing arts hall located within the building of the Atatürk Cultural Center (AKM) in Istanbul's Beyoğlu district. It was completed and opened for use in 2021 as part of the reconstruction project carried out by the Ministry of Culture and Tourism of the Republic of Türkiye. The venue has been allocated for use by various art institutions, primarily the Istanbul State Opera and Ballet Directorate.

Physical Location and Administrative Affiliation

The hall is located in Taksim Square, a central area of Istanbul, as part of the Atatürk Cultural Center complex. The Atatürk Cultural Center is affiliated with the Ministry of Culture and Tourism, and the operation of the hall is managed within this framework. The building was constructed in place of the old AKM, which opened in 1969 but was later closed due to functional and physical inadequacies.

Structural and Acoustic Features

The Türk Telekom Opera Hall is located at the center of the main facade of the Atatürk Cultural Center building, facing Taksim Square. The facade is covered with 15,000 specially produced ceramic pieces, making this arrangement the most distinctive architectural element defining the Opera Hall from the outside.

The interior structure of the hall has been planned in a horseshoe shape, based on physical, technical, and acoustic analyses. This form was preferred, especially in terms of natural acoustic distribution and reverberation time control. The venue has been designed to meet acoustic parameters such as reverberation time and sound clarity, which are sought after in international opera houses.

Interior Acoustics and Material Selection

Side wall coverings have been specially designed according to acoustic needs to balance reflection and absorption. As flooring material, highly sound-absorbent textile products have been avoided; therefore, wooden flooring has been used throughout the hall. The preference not to use sound-absorbing elements like carpets or soft floor coverings aims to preserve reflected sound.

The seat structure is covered with textile fabrics having appropriate airflow resistance to balance sound transmission and absorption. Additionally, sound-absorbing panel components are located on the underside of the seats. This design has been developed to ensure that sound behavior is not distorted even when the hall is empty.

Hall Geometry and Audience Distribution

The hall has a parterre and two balcony levels, with a total seating capacity of 2,040. An elliptical plan has been implemented, providing direct stage views for all spectators. The seating arrangement is tiered to reduce sightline obstruction and maintain central stage focus.

Orchestra Pit and Stage Equipment

The orchestra pit has been designed to accommodate an orchestra of 85 people, with a size of approximately 125 m². This area is positioned to provide access from the lower floor, integrated with the stage.

Elevator floor systems on the stage allow for the simultaneous lowering and raising of sets. This system enables rapid transfer of preparations made in the set loading area to the stage. Similarly, movable areas are available on the side stages for set installation and transitions.

Lighting System

The lighting system located on the hall ceiling consists of special glass pieces shaped by the blowing method. This system can be fully recessed into the ceiling so as not to visually compete with the stage during performances. Furthermore, it operates with a movable digital command infrastructure that can be integrated into choreography, capable of creating synchronous visual unity with the stage when needed.

Construction Process and Architectural Design

The Türk Telekom Opera Hall, constructed together with the Atatürk Cultural Center (AKM) building, was designed as part of the reconstruction process initiated in 2019. The design of the structure was carried out by architect Murat Tabanlıoğlu. Tabanlıoğlu is also the son of Hayati Tabanlıoğlu, the architect of the original AKM building completed in 1969. In this context, while the structure references some architectural principles of the previous building, technical, static, and functional conditions were prioritized during the construction process.

Architectural Design Approach

The new AKM building maintains the facade composition, layered mass relationship, and central stage placement of the original structure, but has been redesigned according to current building regulations. During the design process, parameters such as the building's earthquake resistance, fire evacuation scenarios, acoustic performance criteria, thermal insulation, accessibility, and public space relationship were decisive.

Beyond aesthetic elements, this structure was shaped based on the spatial arrangement of public cultural units and the infrastructure requirements for performing arts. The opera hall is one of the units integrated into the building's front facade, positioned harmoniously with the main load-bearing elements of the building, both architecturally and technically.

Construction and Implementation Process

Construction activities for the AKM complex began in early 2019 and were completed within approximately two years. The construction process was carried out under the coordination of the Ministry of Culture and Tourism, through various subcontractors and technical consulting firms. The construction phases were implemented under four main headings, including shell structure, interior layout, mechanical-electrical infrastructure, and installation of stage technologies.

During the construction process, no restoration or adaptation methods were applied to preserve the previous structure; instead, an entirely new building was constructed.

Usage and Event Programs

The Türk Telekom Opera Hall is a performance venue located within the Istanbul Atatürk Cultural Center (AKM), with its programming largely managed by the Istanbul State Opera and Ballet Directorate. In addition, it is also used periodically by the Istanbul State Symphony Orchestra, the General Directorate of State Theatres, and various private or international art organizations. The use of the hall is planned in accordance with the seasonal calendars prepared by the Ministry of Culture and Tourism and its affiliated art institutions.

Ticketing and Audience Access

Performances held at the Türk Telekom Opera Hall are offered to the audience through ticket categories priced according to different seating arrangements. Seating arrangements are classified based on location and viewing angle, including parterre, first balcony, and second balcony. Each seating area is divided into different pricing groups based on its internal positions.

This application has become one of the examples in Türkiye within the scope of private sector-supported naming models for state structures.
