The SANCO Reference Award 2025 has been awarded to isophon glas of Hannoversch Münden for its contribution to the residential development Eleven Decks in Hamburg’s HafenCity. The jury recognised the project for its technical glass solution, architectural integration, and its ability to combine high living comfort with certified sustainability in a dense urban context.

Developed as one of the largest privately financed residential projects in HafenCity, Eleven Decks comprises 306 apartments arranged above a ground-floor retail base. The stepped building mass rises to 11 storeys, offering a diverse residential programme that includes one-room apartments, multi-room units, and a penthouse level with landscaped roof terraces. Shared amenities such as co-working spaces, fitness and yoga rooms, a club-style communal area with open kitchen, barbecue facilities, and a green inner courtyard support a contemporary, community-oriented living concept.

Designed by CARSTEN ROTH ARCHITEKT, the project has already received the German Design Award 2024 and Residential Buildings of the Year 2025, while achieving BREEAM “Excellent” certification, confirming its strong ecological and socio-cultural performance.

From a façade perspective, the glazing solution plays a decisive role in meeting both comfort and sustainability targets. isophon glas supplied a high-performance triple-glazed insulating glass unit, designed to deliver very good thermal insulation, effective sound reduction, and high daylight transmission, critical factors in HafenCity’s busy, waterfront environment. On the street-facing loggias, the system was enhanced with a suspended impact pane equipped with an anti-condensation coating, ensuring clear visibility, reduced surface moisture, and long-term façade quality.

The jury noted that the façade demonstrates how advanced glass technology can be precisely adapted to architectural requirements, achieving a balance between transparency, protection, and energy efficiency without compromising design intent.

Founded in 1979, isophon glas is a family-owned specialist employing around 200 people, producing insulating glass, laminated safety glass, and toughened safety glass for demanding projects across Europe. The award underlines the company’s long-standing expertise and its alignment with SANCO’s focus on quality-driven, sustainable glazing solutions.

Established in 2024, the SANCO Reference Award highlights exemplary projects by SANCO partners, assessing not only design and performance but also workmanship, logistics, and responsible construction practices, criteria clearly met by Eleven Decks.
