The complex is situated on the edge of Frankfurt’s Bahnhofsviertel (station district) overlooking the Gallusanlage park. It comprises an office tower, a residential tower, and a base structure, each with its own distinct architectural identity, yet forming a cohesive whole. Setbacks and staggered heights reduce the perceived mass and reference the historic villas in the surrounding area. Transparent ground-floor zones housing restaurants, a hotel, an art forum, and a passageway enliven the public space along the adjacent streets.
The office tower is articulated by vertical incisions into slender volumes, creating terraces, roof gardens, and "city windows." At its summit is the publicly accessible Sky Park. The residential tower complements the composition with a calm, slender form and wraparound balconies. The residential concept combines subsidized and privately financed apartments, as well as innovative living spaces with communal areas for diverse user groups.
Access is provided via separate entrances for the office, hotel, and residential units, creating clear addresses and independent functions. An urban passage runs throught he podium, and leads to roof terraces and cultural spaces. Public spaces such as the Forum, Multiroom, Makers' Café, and exhibition areas strengthen the connection to Frankfurt's art and culture scene.
The project places great emphasis on sustainability, flexibility, and circularity. A modular facade and structural system allows for long-term adaptations to the building's use. Materials from existing buildings are reused, while new components are designed for disassembly and recycling.
A low-tech building concept combines passive shading, natural ventilation, photovoltaics in facade louvers and roofs, as well as geothermal energy and heat pumps. Rainwater harvesting, climate-resilient planting, and biodiversity-promoting open spaces complement the overall sustainable concept. The result is a future-proof building that unites architecture, urban life, culture, and ecological responsibility.
