Designed by Japanese architect Sou Fujimoto, the House of Music, Hungary opened its doors to visitors on Sunday with concerts by musicians of the Liszt Ferenc Music Academy.

It is part of the ruling nationalist government’s huge project of transforming Budapest’s City Park into a showcase of Hungarian culture, which was entangled in political controversy due to its hefty costs and the loss of some green areas.

The building, some say, resembles a giant mushroom with its perforated roof that channels light to all its levels via 100 so-called “light wells”, or large holes.

It has a 12m-high continuous glass wall that consists of 94 pieces in a zig-zag arrangement that reflects back sound, creating homogeneous acoustics with uniform sound quality everywhere, its designers say.

“The glass walls are not placed in a parallel way but it is a zig-zag surface where the sound is broken,” said operations director Marton Horn.

“Behind the concert stage a glass surface was created which can be adjusted. There are about 1m-large glass panels which can be individually adjusted, and with this the sound can be channelled up towards the ceiling where the sound is absorbed.”

The building houses a concert hall, several music venues, interactive exhibitions, and a library. Its huge glass surfaces blend the borders between indoors and out, between the natural and the built environment.

“I like the building. Many were built amid controversy – why there, and why in that way? But I do like it,” said Daniel, one of the first visitors.

The House of Music recently won the “Best Use of Music in Property Development” at the Music Cities Awards. It features on the list of “best new things in the world in 2022” by “Time Out”.
