The Gymnasium Lärchen by Flubacher Nyfeler Partner Architekten is a carefully integrated addition to the Lärchen school complex, respecting its 1950s architectural heritage while introducing a modern, sustainable structure. Positioned to reinforce the site's spatial coherence, the compact gymnasium minimizes its above-ground volume, embedding most functions underground to preserve the existing outdoor spaces. A gabled roof and subtle façade articulation ensure harmony with the surrounding residential area, while a hybrid construction of recycled concrete and timber reduces environmental impact. The interior balances functionality and warmth, with a clear, efficient layout that enhances usability. Through thoughtful material choices and a contextual approach, the project seamlessly extends the legacy of the school while creating a flexible and durable space for future generations.
