Berlin is poised to make history with the completion of the Estrel Tower, a mixed-use building standing 577 feet (176 meters) tall. This structure will become the tallest nontechnical building in the city and mark its debut into skyscraper architecture.
Skyscrapers typically rise above 150 meters, as defined by the Council on Vertical Urbanism. The Estrel Tower will be Berlin’s first to meet this criterion. It is expected to open at the end of 2026, housing a hotel, workspace, gallery, restaurant, and bar, making it a new urban destination in Neukölln.
Designed by Barkow Leibinger, a Berlin architecture firm, the tower represents a significant shift for a city known for low-rise constructions and strict height restrictions. This move happens amid debates on adapting and reusing existing structures for sustainability, with advocates emphasizing the importance of retaining the carbon embedded in old buildings.
Gordon Gill, architect of Jeddah Tower, the world’s tallest upcoming skyscraper, told Newsweek about the potential for architectural innovation through enhancing existing buildings. Other architects shared concerns with Newsweek that demolition might compromise Germany’s historical character.
Frank Barkow, founder of Barkow Leibinger, maintains that tall buildings can contribute to a sustainable urban future if thoughtfully designed. While initially having a larger carbon footprint, compact development, efficient land use, and multifunctionality provide long-term benefits.
A Singular Landmark in Berlin’s Urban Landscape
Barkow emphasized that the Estrel Tower is not part of a skyscraper cluster but acts as a solitary landmark within Berlin’s cityscape. Historically, Berlin maintained a 22-meter cornice height, so the tower stands alone amidst lower structures.
Unlike New York or Frankfurt, the Estrel Tower serves as a lighthouse, a beacon for Berlin. It complements the Estrel Hotel across the street, forming a gateway to the city. The development integrates lower structures around the tower.
The design utilizes geometric forms, offering freedom to explore diverse shapes like triangles and parallelograms, likening the approach to a Tangram puzzle. This composition forms a dynamic family of shapes engaging with the surroundings.
Sustainability and Construction Challenges
The tower features a striking façade with metal fins for solar shading, smart glazing, and operable windows. It employs low-carbon energy, water retention systems, and a green roof, optimizing daylight while reducing energy use, aiming for LEED Platinum certification.
One significant challenge was logistics, needing thousands of tons of concrete, including a thick foundation slab. Berlin’s limited experience with such projects required off-site manufacturing of components like the façade and atrium roof to expedite construction.
Addressing criticisms about tall buildings’ carbon footprint, Barkow stated that tall structures, while initially less eco-friendly, prove more compact and energy-efficient over time compared to urban sprawl. Height offers flexibility, supporting diverse uses and freeing land for public amenities.
A New Era for Tall Buildings in Berlin?
Estrel Tower might remain unique or herald a new age of skyscrapers in Berlin. Barkow foresees it as a potential precedent, arguing for tools fostering diversity, development, and social centers. Tall buildings, as he sees it, contribute to Berlin’s growth.
Barkow commented, “Berlin can be both tall and true to its historical scale. That combination is the city’s future.”
