Environmentally friendly, architecturally and visually timeless, and above all full of the latest technologies. Such will be the building of the new Ostrava concert hall, which was recently ranked among the 10 most anticipated buildings in the world by the prestigious magazine Architizer. Its authors from the studios Steven Holl Architects from New York and Architecture Acts from Prague have just completed a study of the building.
Among other things, they aim to use maple wood or low-energy glazing. The House of Culture of the City of Ostrava itself will also undergo changes, and will newly offer complete background facilities for the Janáček Philharmonic Orchestra in Ostrava, rehearsal rooms, an educational center and a recording studio. Now that another part of the project documentation has been completed, the city of Ostrava is another step closer to its new concert hall.
"We are very pleased that the completed study is already on the table and we're proud to say that in addition to being exceptional in its visual solution, the building also promises ecological sustainability, which brings Ostrava back to the forefront of world interest,"
The project envisages a number of ecological solutions. These include the use of insulating low-emissivity glass, recycled and recyclable materials, and especially an energy concept of cooling and heating. The design team works with several variants using heat pumps of closed or open systems.
“Patinated 100% recyclable and highly flexible zinc will be used to cover the hall. Paneling made of gray glazed maple wood, which is commonly used, among other things, for the production of violins, will ensure perfect accoustics inside the hall. On the same floor as both halls, there will be a special storage room for pianos with a constant temperature and humidity, from which the nearly half-ton instruments will be transported directly to the stage using special wheels,"
Another interesting feature is the way in which daylight will enter the building. It will feature a system of skylights, which will be able to be dimmed.
The study of the new extension of the hall with a capacity of 1,300 seats, which will also include a glazed vestibule or a café, furthermore envisages the reconstruction of the existing social hall in the culture house into a chamber space with a capacity of 475 seats.
"The chamber space as well as the large hall can be adapted to the needs of individual artists, orchestras or other users of the halls. Both stages will be composed of movable panels; the chamber hall will also feature a sliding wall that will provide the option to increase or decrease the size of the stage. Both halls will be suitable even for amplified, i.e. sounded music,"
the director of the Janáček Philharmonic Ostrava, Jan Žemla, describes the wide range of uses of the new concert venues.
According to Deputy Mayor Zuzana Bajgarová, the documentation for the building permit is already being prepared, it could be ready at the end of next year. In 2022, the preparation of documents for tendering as well as the tendering itself shall take place, followed by the signing of the contract, whereupon the construction process shall commence. The construction is currently estimated at 32 months. That means that the new concert hall should be completed in 2025.
The cost of the entire project and its construction process is estimated at 2.2 billion crowns. The city government of Ostrava still counts on the help of the Moravian-Silesian Region in the amount of 300 million crowns; the state should contribute 600 million.
