The ZIN in Brussels wins the International High-Rise Award 2026/27

The winner of the International High-Rise Award (IHA) 2026/27 has been chosen: The ZIN mixed-use high-rise in Brussels, designed by the architectural practices 51N4E, l’AUC and Jaspers-Eyers Architects, has won the competition for the world’s most innovative skyscraper.
The prize consists of EUR 50,000 and a statuette created by the internationally renowned artist Thomas Demand.
Representing the architects at the award ceremony were Johan Anrys and Olivier Cavens of 51N4E, Alessandro Gess and Djamel Klouche of l´AUC and John and Loik Eyers of Jaspers-Eyers Architects, Jean-Philip Vroninks attended on behalf of the developer Befimmo. The award was presented at a formal ceremony in Frankfurt’s Paulskirche by Dr. Ina Hartwig (Deputy Mayor in charge of Cultural Affairs, City of Frankfurt), Birgit Dietl-Benzin (Member of the Board of Management of DekaBank) and Peter Cachola Schmal (Director of Deutsches Architekturmuseum).
The ZIN represents not only an architectural renewal but also a paradigm shift in high-rise construction: Instead of demolition and new construction, the focus now is on transformation, resource conservation, and mixed-use development. The two former World-Trade-Center towers were not completely demolished; their service cores and the basement levels were retained and integrated into the new building. A slender structure was inserted between the two towers, connecting them to form a single building. Today, ZIN serves a variety of purposes, and parts of it are freely accessible to the public. Sports clubs train in the gym; the building also houses apartments and a hotel, as well as a huge rooftop garden, and a greenhouse that is also used by the hotel’s café. The Flemish government has relocated its headquarters to ZIN.
The project marks the starting point of a comprehensive revitalization of Brussels’ North Quarter. Its mixed-use design opens up to the city and its residents.
The jury’s focus: A high-rise building should be a „good neighbour“
The jury for this 12th International High-Rise Award focused on the question of what role high-rises might play in the future. Regardless of aesthetics and function, the jury agreed that a high-rise building’s ability to “be a good neighbor” is of fundamental importance. In other words, a high-rise building should give something back to its surroundings, enhance the context in which it stands, and benefit both the city in which it was built and the people who

live there. The jury’s starting point was the idea that the winning high-rise should still be relevant fifteen years in the future. An additional question increasingly relevant in the European context, concerns refurbishment: how can high-rises be transformable and how can they accommodate a variety of uses. The jury agreed that, if high-rises are “good neighbors”, it is crucial to promote towers that are not monofunctional but instead help revitalize city centres and central business districts.
As a result, the jury unanimously selected ZIN in Brussels, Belgium, as the winner of the International High-Rise Award 2026/27. Brian Yang, as chair of the jury and the winner of the IHA 2024/25, captured the reasoning as follows: “High-rises are no longer all about being a tall symbol of power. They are about the power to transform, to change, to respond to a situation. I think it’s important for a neighborhood to be full of life, and that can be achieved with a mix of offices, hotels, and apartments, like at ZIN.”
ZIN is boosting the neighbourhood in which it is located
the jury agreed, that ZIN presented by far the most compelling overall narrative: It showed how the idea of refurbishment could be taken to new heights and given a new quality. In addition, ZIN is exceptionally large by European standards. With its 10,000 square meters of floor space, it serves as a major draw in a less attractive neighbourhood and, ideally, will stimulate further construction activity.
The jury concurred that, while the building might not be an incredible eye-catcher in aesthetic terms, this was precisely what made it stand out: Its ability to “do so much”, as Peter Cachola Schmal put it, without trying to be iconic. Brian Yang, as chair, confirmed this assessment: “It seems like an amazing project that does everything a high-rise can do in a positive way: Through a process of transformation, it brings meaning and quality to the area, thereby strengthening the entire neighborhood. It enhances the surrounding area and features a wonderful internal topography. The transitions between public and private spaces are exceptionally well executed.”
The project rejects the strident claim of “Here I am” and instead emphasizes on getting the message right. Whereas many of the high-rises in Brussels are classic glass-and-steel monoliths, ZIN breaks completely with that idea. The two original World-Trade-Center high-rises that stood here were stripped back to their cores and redeveloped by embracing between them an intervening new structure with double-height floors, designed to encourage mixed use, both vertically and horizontally. Offices, residences, hotel rooms, retail, and green spaces are interwoven to create a coherent unit that is never “dead” at night. The new glass podium building to one side and the connecting tower, with differently spaced ceiling slabs, add diversity to the new/old build. The project achieved Cradle to Cradle certification for 95 percent for the new materials used. This represents a closed loop – endless raw material cycle rather than a waste one – a figure never before achieved for a European mixed-use project of this size.
