Maintaining the historical identity

Die Glocke, a UNESCO World Heritage Site and historic concert venue, required an expansion to improve its infrastructure while preserving its cultural and architectural integrity. The challenge was to modernize logistics, accessibility, and spatial flexibility, without compromising the building’s heritage.

Our design concept aims to serve musicians, audiences, and event organizers by enhancing user experience and operational efficiency. The design maintains the historical identity while integrating sustainable and adaptive solutions for long-term use. The new extension mirrors the west wing of the existing building along the central axis, both formally and functionally. The new space features a hybrid timber construction within a contemporary brick shell that blends carefully into the context. Thoughtful urban integration enhances public accessibility while strengthening the main entrance.

Mirroring as a concept

Inspired by Bremen’s Hanseatic “Fachwerk” architecture, the extension features a triangular pattern reflected in the façade relief, windows and structure. The project uses mirroring as a concept for volumetrics, circulation, and detailing to create harmony and reflection between old and new. The ground floor opens to the public space, between the front façade and the garden shared with the Cathedral, strengthening flexibility and urban connectivity. 

A new feature staircase in the East wing mirrors the existing stairs, while greatly improving public accessibility. The musicians are at the core, with a new acoustically optimized Music Experience Room (MER), restructured backstage areas, and improved accessibility. Sustainability is embedded through a CO₂-conscious hybrid timber construction, a photovoltaic-integrated roof, and rainwater management solutions.

Traditional brick with modern glazing

The expansion respects the historical fabric while introducing contemporary elements. The facade combines traditional brick with modern glazing for an inviting yet contextually sensitive presence. The MER’s pentagonal form fosters an immersive musical experience with adjustable acoustics and flexible seating for up to 650 people. The Music Club spreads over two floors with a separate entrance from the street. A restructured foyer enhances audience circulation, while a dedicated artist entrance improves operational efficiency. 

Public outdoor areas are reimagined with greenery, flexible event spaces, and pedestrian-friendly surfaces. Energy efficiency is prioritized through geothermal heating, hybrid ventilation, and intelligent lighting systems.
