Chalupkova Bratislava Architecture & Urban Design Competition

Summary of the competition

A total of 83 proposals from all over the world were submitted in the competition. The international scope of the participants resulted in many unique approaches in their designs.

The aim of the competition was to find a future solution for a project in Bratislava's city centre, at the corner of Mlynské Nivy, Košická and Chalupkova streets. The winning design will complement the rest of the site, where the first office building is already under construction.

The site in question is situated in the most valuable and vivid location – in the newly emerging Bratislava’s downtown – right in the dynamic business quarter with close proximity to the historic city center and Danube River.

The jury assessed the suitability of the proposed urban structure for the area, the added value it would provide to the city and its inhabitants, as well as the quality it would offer its future residents and retail clients.

Winning Proposal

Stefano Boeri Architetti

The proposal represents a contextual approach in designing an urban structure based on the compact block characteristic European cities, in contrast to the solitary developments in other parts of the newly emerging Bratislava downtown. The project offers diverse architecture of its individual buildings and an open inner block that builds on the public green spaces of the neighbouring developments. This connection will create one of the largest parks in Bratislava.

Stefano Boeri, the Founding Partner of Stefano Boeri Architetti, explains their approach to the proposed design concept. “The Urban Oasis project brings to the modern district of a dynamic city a wide public garden with high plant biodiversity, surrounded by a frame of residential buildings and citizen services. Designed as a new centrality for Bratislava, open and permeable to the flows of everyday life, Urban Oasis best represents the challenges of the contemporary urban world and an additional step towards the idea of an archipelago metropolis: a city where neighborhoods are nuclei of clean energy production, with the variety of functions and inhabitants typical of European cities and the living nature of plants at their centre and on the façades of buildings.”

“In the Urban Oasis project*, we worked on how to generate architectural quality in a formerly industrial urban area undergoing a major transformation; on how to optimise direct natural light, while at the same time protecting it from wind and noise pollution; on how to enhance the accessibility and usability of the park, while maintaining its character as a ‘secret garden’; on how to transform it not only into a flexible and high-quality public space, but also into an important element in regulating the microclimate, humidity and urban heat island effect. We are very satisfied with the project and believe that it can really become an added value for the neighbourhood, the city and all the inhabitants.”, adds Pietro Chiodi, Partner in Charge of the Stefano Boeri Architetti studio.

The project will provide the area with approximately 1,300 apartments in four residential buildings and approximately 45,000 sqm of leasable office and retail space.

“Until recently, the institute of architectural and urban planning competitions with similar international participation, scope, and quality was not common in Bratislava. Today, the situation is different, and the participation of foreign studios highlights the growing potential and significance of our capital city. I firmly believe that the Chalupkova zone, one of Bratislava’s most prestigious locations near the city center, definitely deserved an architectural competition. As a developer, we are committed to the final product; it represents our brand and reputation. Therefore, I am pleased that we are returning to this locality with a new project by Stefano Boeri Architetti. Together, we will once again elevate the quality and standard of real estate development in Bratislava.”, said Juraj Nevolník, Managing Director of Penta Real Estate.

The Italian studio designs award-winning projects all around the world. Among their most renowned works are the Bosco Verticale residential complex - the Vertical Forest in Milan, and Villa Méditerranée in Marseille. Bosco Verticale stands as a prototype of architecture that integrates living vegetation and has received numerous international awards. The Council on Tall Buildings and Urban Habitat recognized Bosco Verticale as the Best Tall Building Worldwide. The studio primarily focuses on sustainable architecture and strategic urban development.

*Urban Oasis is not the final naming of the project. This naming served just as the working title, under which the architects submitted the project to the competition.


The 3-hectare building site is one of the most prestigious locations in Bratislava, situated in the newly emerging downtown, in close proximity to the Danube River and the Old Town.

Historically, this zone was dominated by significant industrial centers. Due to its economic importance, it became a target of the first air raid on the city during World War II. As a result, the area was partially abandoned and over time, the factories ceased operation.

We aim to transform this long-neglected zone, into a vibrant area with world-class architecture, prime residential and commercial spaces, as well as high-quality public spaces with greenery, all while maintaining a strong emphasis on the environment.

In the Chalupkova development zone, Penta Real Estate has previously completed the successful SKY PARK by Zaha Hadid project, which also involved the revitalization of a national cultural monument - Jurkovič Heating Plant.
