The interior project for common part of the House of Music included modifications of 3 concert halls (Suk Hall, Small and Chamber Hall), a common foyer over two levels, main entrance, facilities for teachers and adjacent outdoor areas. The reconstruction also included a complete replacement of technological equipment and new sound and stage lighting.

The building was built in the 1980s, originally as the seat of the local Communist Party department, according to the project of Jan Třeštík, the author of the interiors was Jan Bočan. After the Velvet Revolution, it was dedicated to music - it is the seat of the Conservatory, Chamber Philharmonic and other music organizations. The aim of the modernization was the overall revitalization of the interiors and their adaptation to the needs of current users. It was necessary to design tailor-made solutions for individual halls, including acoustic measures, new surfaces, equipment and furniture.

All rooms were equipped with air conditioning and new lighting, some rooms also underwent layout changes for better operational connections, clarity and orientation. This mainly concerned the school part, where a new reception was built on the site of the canceled staircase.

The design also included a tailor-made orientation and promotion system, planting greenery instead of felled trees, and repairing and cultivating adjacent outdoor terraces, flower beds and courtyards.
