For decades, the Kontrastwerk in Ehrenfeld served Deutsche Bahn's logistics needs. Today, strategic infrastructure investments and thoughtful renovations—alongside selective new construction—are breathing fresh life into the site as a dynamic workspace. Through successive phases, flexible office spaces, showcases for creative work, and spacious production facilities continue to take shape. Project LH 0418, conceived by raumwerk.architekten, transforms the iconic "Long Hall" into a series of loft offices, each with its own distinct spatial character and appeal.

Aurelis Asset oversaw the phased conversion of the former warehouse. Across its 23 bays and multiple construction phases, the building was meticulously adapted for different tenants. The vision was clear: create a denser, more accessible destination that honors its industrial heritage rather than hiding it—weaving history intentionally into the new narrative. The adaptive work reinforces and reveals the distinct typologies already present in the original structures. Coordinated wayfinding and landscape design elements unite the buildings thematically across outdoor spaces. The result is a thoughtful, sustainable transformation unfolding gradually while the site remains in active use. By engaging users directly in the planning process, the team has developed innovative spatial configurations that respond to real working needs.

Drawing from the building's structural logic, the "Long Hall" was reorganized into three distinct spatial zones. The original structure was carefully preserved, while the façades were replaced with energy-conscious post-and-beam systems. Strategically positioned skylights flood the deep interiors with natural light. Within this uniform structural framework, each of the three units gained distinctive spaces with its own character. Picture light-filled offices with soaring ceilings, a sculptural wooden staircase inviting gathering and conversation, a two-story meeting pavilion—even a salvaged shipping container reinterpreted as a room-within-a-room. Throughout, existing concrete beams are celebrated as architectural elements within the bright, open office floors. This restrained aesthetic embodies a philosophy: materials remain honest and exposed, and the creative tension between old and new is left beautifully visible.
