Text description provided by the architects. The genesis of the project arose from a fascination with the geometry of the spiral. A shape that has inspired humanity for centuries, it appears in nature at all scales: from protein molecules to the structure of galaxies.

In what way does this geometry represent Polishness for us and its inherent spirit of innovation? The borders of Poland's territory do not hinder innovative ideas from spreading far and wide, influencing distant regions, and allowing knowledge gained abroad to return to the gravitational centre of our nation. These invisible but significant forces for the country's development are expressed in the dynamic form of spiral walls, with the concert hall at its core.

This hall, inspired by Baltic amber—a symbolic material of Poland—is enclosed by a curtain of golden chains evoking willow branches, referencing the landscapes that inspired Chopin. This curtain unifies the space, conceals entrances, and creates an intimate atmosphere subtly accentuated by lighting. The pavilion exclusively utilizes locally sourced Japanese pine wood for both its structure and cladding, capitalizing on the exceptional savoir-faire of Japanese carpenters. It references traditional techniques reinterpreted through contemporary methods, resulting in a vibrant façade that shifts appearance throughout the day due to the interplay of shadows. Inside, the timber provides warmth, sensory comfort, and even an aromatic presence.

The construction employs a modular logic based exclusively on two types of wooden modules. This strategy ensures flexibility to adapt to the project's geometry while maintaining rigorous construction standards to meet extremely tight deadlines.

Under the slogan "Heritage that drives the future," the project establishes a dialogue between national identity and local context, between traditional craftsmanship and forms that embrace the future.
