Onyx

In the very heart of Sofia lies ONYX – an ambitious and innovative project that combines modern architecture with the latest construction technologies. This impressive building is not just an office complex, but a symbol of the future in sustainable and energy-efficient construction. The building’s architecture is bold and clean, with a focus on spaces that allow in as much natural light as possible, creating a sense of openness and freedom. But it’s not only the exterior that makes ONYX special – it’s also how the project fits into the concept of green and sustainable buildings, which is a core objective of the investor. Every architectural decision and choice of materials has been carefully considered to ensure minimal environmental impact.

Designed by PROARCH AD with Alumina Elit 2003, the building expresses a clear architectural vision - Alukönigstahl systems were specified to realise that intent while meeting demanding performance targets.

Located in Sofia, Bulgaria, Bulgaria, this office project demonstrates how the right combination of window, façade and shading systems delivers measurable performance in a real architectural context.
