An international competition has chosen Hosoya Schaefer Architects and its team to lay the groundwork for the masterplan of 65 hectares on the Danube. The winning scheme puts public space, landscape and industrial heritage ahead of individual buildings.
Bratislava has selected the design that will become the basis of the Winter Harbour masterplan, one of the last large redevelopment sites in the wider center of the Slovak capital. The result was announced on November 9; the winning project was presented to the public the following day, and since November 11 it has been on display alongside the other six finalists at the TU-BA center. The sequence of dates matters: this is not the start of construction, but the shift from a broad vision to a planning tool meant to steer a long and complex transformation.
The competition, launched by the state-owned company Public Ports and the City of Bratislava and organized by the Metropolitan Institute of Bratislava, drew 123 entries from 33 countries. After an initial shortlist, seven teams developed their proposals in an anonymous second stage. The jury unanimously chose the consortium led by Zurich-based Hosoya Schaefer Architects, with Gillespies for landscape and green-blue infrastructure, ARGUS Studio for mobility and Körting Ingenieure for engineering and flood protection. KCAP came second and Cobe third.
Sixty-five hectares read as a single system
The Winter Harbour covers about 65 hectares: 45 on land and roughly 20 on water, spread across the port basins and the edge of the Danube. It is a place where industrial scale, fenced-off quays and riverside vegetation sit side by side without yet forming an accessible part of the city. The winning design refuses to treat this condition as a blank slate. The structure of the port becomes the framework of the new district, while buildings, parks, routes and uses are organized around the distinct identities of each peninsula and basin.
The plan includes a riparian park on the southern peninsula, a Marina Park near Warehouse 17 and a Cultural Park on the central peninsula. Housing, offices, culture, sports and services alternate along a continuous network of waterfront promenades. The industrial remains are not treated as isolated backdrops to be preserved, but as infrastructure to be brought back into use: cranes, warehouses, quay edges and existing structures are meant to give scale and character to the public spaces.
This is where the project is at its most convincing. Before deciding what individual buildings will look like, it defines a shared geography: the relationship with the water, the continuity of the promenades, the location of community facilities and the hierarchy of parks. It is a useful method for any large brownfield site, because it shifts value away from the sum of real-estate developments and toward the quality of the relationships that hold them together. In Italy, the same question runs through many of the projects in our roundup of former factories reclaimed by architecture: adaptive reuse really works when heritage becomes a framework for new uses, not just a recognizable image.
In the Winter Harbour masterplan, landscape is not decoration
The makeup of the winning team clarifies another point: landscape, mobility and flood safety are built into the project from the outset. The Danube is not just the most attractive backdrop for renderings. Its presence demands careful coordination of permeable ground, planting, levels, access to the basins and flood protection. So-called green-blue infrastructure therefore ties together environmental quality and the way the city actually works, so that parks and waterfronts are not tacked on afterwards as compensation.
Mobility, too, is set out before any detailed architectural design. The future masterplan will have to favor walking, cycling and public transit, connect the district to the existing city and manage coexistence with port operations. Cargo handling will gradually move to the nearby port of Pálenisko, but the transformation will need to keep the logistics system running through each phase. For designers and public authorities, it is a concrete reminder: a new neighborhood does not become sustainable because there are trees in the renderings, but because it coordinates timing, infrastructure and uses without disrupting the economic life of the place.
From competition to rules that stand the test of time
The result does not yet mean a district under construction. According to the Slovak daily Denník N, the Minister of Transport has pointed to a horizon of at least five years before work begins, while the full transformation could take decades. In the meantime, the winning team must turn its proposal into a masterplan, prepare more detailed studies for the main public spaces and draft a design manual capable of ensuring continuity across phases and different architects. Further architecture competitions will follow.
This gap between image and delivery does not weaken the news; it defines what makes it interesting. The job of the masterplan will be to establish what should not be renegotiated plot by plot: public access to the water, ecological continuity, the presence of services, the quality of the ground floor, the protection of heritage and the balance between built volume and open space. It is the same question that comes up whenever we ask what the cities of the future will look like: not which form will look newest, but which rules can produce livable environments over time.
Public consultation continues on November 23 and December 7, and the seven finalist projects will remain on display until January 31, 2027. This is an important step, because it makes the competition the start of a conversation rather than its conclusion. The Winter Harbour will be credible if its promised openness does not remain a graphic quality of the drawings but becomes a verifiable condition: reachable riverbanks, continuous parks, reused industrial buildings and a neighborhood able to welcome residents, work and culture without privatizing the relationship with the Danube.
