National Opera and Ballet

The National Opera and Ballet was awarded with a special prize in the “Building of the Year” contest. The investment is made by the Ministry of Culture and EKSA was the prime contractor. The project of reconstruction and adaptation, made in 2007 by arch. Konstantin Peev and EKSA team, includes innovative construction technologies in Bulgaria. The concert hall and corridors are air conditioned. The slope of the floor and balconies have been changed and the spacing between seating lines is increased by 0.20 meters. It was achieved by using a raised floor with light construction in order to minimize the burden on the consoles that forms the balconies. The design is elegant and light and covered with new acoustic flooring.

Arch. Konstantin Peev, manager of EKSA PLC:
“The new law does not encourage the preservation of cultural heritage”

Restoration of a building as the National Opera and Ballet is a great challenge. Most specific for realization was the space for orchestra, the new air conditioning system and reconstruction of the electrical installation.
Regarding the legal basis, it is still lacking support for buildings – cultural heritage. In the draft version of the law, there is nothing that stimulates the policy for protection of the cultural heritage. It cannot be fully cared by the state. Part of the taxes, which are paid, should be intended for heritage. Much of the tourism is associated with cultural and historical heritage, and nothing is secured for their protection. Therefore, a percent should be allocated for maintenance of these objects. World practice says that between 2-3 percent of revenues from tourism should be allocated for cultural heritage.
