For many years, Bratislava has been evolving primarily inward, through the gradual transformation of its existing urban fabric. Alongside smaller-scale developments, however, there are also sites with the potential to fundamentally reshape the functioning of the entire city. One of them is the former Istrochem industrial complex — the largest brownfield site in Bratislava, covering approximately 1.6 million square meters.
The site, which remained closed to the public for decades and was primarily associated with industrial production, is now entering a new stage. This is not, however, the presentation of a specific development project or a final urban design proposal. Rather, the professional groundwork is now being laid for the site’s future transformation into a fully-fledged urban district with housing, public spaces, public amenities and greenery.
Penta Real Estate, which has long-standing experience in the transformation of large-scale sites in Bratislava, is joining the process as an expert partner in developing the urban planning framework. However, the process is not intended to take place solely behind closed doors among experts. Public participation will also form part of the preparations, helping to shape the future character of the area.
The need for open dialogue has given rise to the Nové Nové Mesto initiative. Rather than presenting a finished project, its aim is to create space for an open discussion about what should take shape in this part of Bratislava. After all, large-scale transformation sites of this kind affect not only their immediate surroundings, but also how the city functions as a whole — from the availability of housing to the quality of public space and everyday life.
Public participation will be an integral part of the process from the very beginning. The preparatory phase will bring together experts in urban planning, architecture and environmental matters, along with local government representatives and city residents. The goal is to establish the strongest possible foundation for future decision-making and to structure the process systematically even before the urban planning competition is launched.
The urban planning competition will represent one of the most important milestones of the entire transformation process. Expected to be announced in 2027, it will deliver a proposal for the site’s future form, which will then serve as the basis for subsequent planning and permitting procedures. The competition entries will be assessed by an expert jury that will also include representatives of the city and the respective city district.
There is growing discussion around how large-scale transformation sites of this kind should function from the city’s perspective. Modern districts are no longer designed as isolated, single-purpose zones, but rather as natural urban environments combining housing, public amenities, services, public spaces and greenery. For this reason, the future transformation of the former Istrochem site is being shaped around the principle of a polycentric city — one that creates a balanced urban environment for everyday life.
The environmental condition of the site remains a key topic. Addressing the existing environmental burden will be an essential part of its future transformation and one of the fundamental prerequisites for any further development. In the case of a brownfield site of this scale, this is a long-term process which requires a systematic approach and coordination across a range of specialist disciplines.
In the upcoming period, the primary focus will therefore be on gathering public input, facilitating participation, and preparing the brief for the urban planning competition. Additional forms of public engagement are expected to follow gradually, ranging from online tools to activities directly within the area itself.
The future of the former Istrochem site is yet to be defined. What is already clear, however, is that its transformation will be one of the most significant urban regeneration projects in Bratislava, with the potential to shape the city for decades to come.
