Winter-readiness in climate-adapted design—that may sound like a field for specialists armed with thermometers and de-icing materials, but it has long been a concern for every ambitious urban planner, landscape architect, and urban designer. Anyone working to make public spaces in Germany, Austria, or Switzerland resilient to summer heat must not dismiss winter as a mere nuisance or off-season. On the contrary: a truly sustainable, climate-adapted design must prove its worth even in sub-zero temperatures, frozen ground, and slush. What does this mean for planning, material selection, vegetation concepts, and expectations for use? And how can we achieve a paradigm shift away from the “summer dream” toward a cityscape that is vibrant and functional year-round?

Winter Readiness as a Touchstone for Climate-Adaptive Urban Planning
Climate adaptation has long been a staple term in competitions, mission statements, and funding programs. Yet in practice, there is often a fatal fixation on summer: shade providers, evaporative cooling surfaces, drinking fountains, and green roofs—all central elements when it comes to heat management. But as soon as the first leaves fall and temperatures drop, interest wanes. Then, snow-removal plans, snow-clearing services, and slip hazards dominate the discussion. Yet the winter months, in particular, should serve as a litmus test for the quality of climate-adapted urban design. Anyone planning open spaces, squares, or new neighborhoods must ask: How do our designs function in slush, frost, and darkness? Where are the shortcomings in accessibility, and how do plants, paving, and street furniture withstand the harsh months between November and March?
The concept of winter suitability encompasses more than just technical operational readiness. It is not merely a matter of ensuring that areas can be cleared and gritted or that sidewalks do not turn into ice rinks. Rather, the question at hand is how open to use, safe, and attractive urban spaces actually remain in winter. The quality of drainage systems, the resilience of vegetation, the visibility of paths, and accessibility for all are not mere luxury details, but central requirements for climate-adapted planning.
A look at Scandinavia shows how naturally winter is integrated into the design logic: seating areas with windbreaks, strategically placed lighting, material choices that withstand frequent freeze-thaw cycles, and vegetation that doesn’t consist solely of bare branches even in January. In Germany, Austria, and Switzerland, such winter-proof designs are still too often the exception—and are frequently treated as additional costs rather than understood as building blocks for long-term resilience.
Yet climate change is also altering the winter months. The spectrum ranges from mild winters with persistent rain to sudden cold snaps, severe frost, freezing rain, or alternating thaw and freeze cycles—all of which put urban trees, pavement surfaces, and drainage systems through a stress test. Planning that ignores winter conditions therefore risks not only functional failures but also significant follow-up costs due to repairs, outages, or wear and tear.
Winter resilience should therefore not be viewed as a burdensome obligation, but rather as a hallmark of climate-adapted planning. It serves as the litmus test for whether a design functions year-round, whether materials, plants, and user interests are harmoniously aligned—and whether the city truly remains accessible to everyone, regardless of weather or season.
Materials, Vegetation, and Spatial Impact: Thinking Year-Round, Designing for Durability
The choice of materials and surface design are at the heart of any discussion about winter suitability. What appears to be pleasantly pedestrian-friendly, glare-free, and low-maintenance in the height of summer can quickly become a hazard in winter. The freeze-thaw cycle, road salt, moisture, and mechanical stress from snowplows place extreme demands on pavers, slabs, asphalt, and joints. Experience shows that cheap materials or improper installation will take their toll by the end of the first winter at the latest, resulting in frost damage, unevenness, or slippery surfaces. High-quality, frost-resistant surfaces with a textured, non-slip finish are not a luxury but a necessity.
Vegetation must also withstand winter extremes. Trees, shrubs, and perennials that can tolerate summer heat are not automatically winter-hardy. Urban trees suffer from road salt, soil compaction, and fluctuating water levels. Careful species selection, sufficiently large tree pits, well-drained substrates, and innovative irrigation technologies that function year-round can help here. Evergreen plantings, textured grasses, or hardy understory plants not only bring color and texture to the dreary months but also provide valuable refuges for birds and insects.
Another key issue is the spatial effect in winter. Darkness, wetness, snow, and ice fundamentally alter the atmosphere of urban spaces. Squares, paths, and parks that serve as lively gathering places in summer can quickly become deserted and uninviting in winter without well-designed lighting, windbreaks, and outdoor furniture. Strategically placed pockets of light, wind-protected seating, and flexible spatial designs that invite people to linger even in the cold and darkness are essential.
It is important to take into account the needs of different groups. Children, older adults, and people with mobility impairments are particularly dependent on safe, clearly visible, and accessible paths. Accessibility does not end at the curb—in winter, it also includes keeping ramps clear, avoiding tripping hazards caused by frozen puddles or uncontrolled grit, and providing orientation through high-contrast markings.
Ultimately, winter-ready design means combining durability with aesthetics. The goal is to create spaces that not only function technically but also foster a sense of identity in winter, offer a pleasant environment, and facilitate social interaction. Planners who take this to heart create genuine added value—and set standards for year-round urban quality.
Technical Strategies and Maintenance Concepts: From Drainage to Snow and Ice Control
The technical requirements for winter-ready open spaces are high—and are becoming increasingly complex in the era of climate change. A key issue is drainage. Heavy winter rain, followed by frost, can lead to ice formation on paths and squares if the water cannot drain away quickly and reliably. Surfaces with sufficient slope, well-dimensioned drainage channels, permeable joints, and retention areas are essential. The placement of drains, the selection of salt-resistant materials, and regular inspection of the systems are also mandatory.
Snow removal and winter maintenance are often viewed as purely operational tasks. However, intelligent planning can significantly reduce the effort and risks involved. Wide main paths that can also be accessed by machinery, clear route layouts, the avoidance of bottlenecks and dead ends, and the provision of turning areas for snow removal vehicles make winter maintenance considerably easier. Selecting plants that tolerate road salt and mechanical stress, as well as avoiding planting trees and shrubs too close to the path, are also important considerations.
Another technical area involves the integration of smart irrigation and drainage systems. Sensor-based systems can not only optimize the care of vegetation in the summer but also help prevent frost damage in the winter through timely drainage or targeted management of excess water. Digital monitoring systems, such as those being tested in pilot projects in Zurich or Vienna, provide valuable data for fine-tuning maintenance and operational procedures.
The use of alternative de-icing materials, such as lava, sand, or gravel instead of conventional road salt, can reduce the impact on vegetation and surfaces. However, these materials must be removed regularly to prevent clogged drains and the formation of fine dust. Innovative approaches, such as heated sidewalks, are still rare and are usually economically viable only at critical points such as entrances or pedestrian zones.
Maintenance plans must be flexible and forward-looking on a seasonal basis. This means: timely pruning before winter, removal of leaves and fallen fruit, inspection of trees for the risk of breakage, and—not to be forgotten—communication with residents and users. Transparent information about planned measures, temporary restrictions, or alternative routes increases acceptance and reduces the risk of accidents.
Best Practices, Public Participation, and Communication Challenges
Those looking for exemplary projects featuring winter-ready, climate-adapted design are increasingly finding them in German-speaking countries as well. In Vienna, for example, parks such as Helmut-Zilk-Park and the Nordbahnhof forecourt are designed to function as social gathering places even in winter: with wind-protected seating areas, durable materials, evergreen plantings, and strategic lighting that creates a sense of safety and atmosphere. In Zurich, new urban neighborhoods are being developed according to the principle of “four-season suitability.” There, winter considerations are incorporated into the design phase from the very beginning—from the orientation of paths to street furniture and the maintenance plan.
A key factor for success is the early and ongoing involvement of users, residents, and operational staff. They often have a better understanding of the actual vulnerabilities and needs during winter operations than external planning firms. Participation formats, such as seasonal usage workshops, feedback apps, or digital twins that simulate various weather scenarios, provide valuable insights for optimizing designs and operational processes.
Communication is an underestimated discipline, especially when it comes to winter suitability. Excessively high expectations regarding year-round usability can lead to disappointment when snow, ice, or wet conditions make temporary restrictions unavoidable. Realistic information, seasonal usage options, and flexible spatial concepts that allow for temporary adjustments—such as mobile furniture, temporary canopies, or changing lighting installations—can help here.
The greatest challenges often lie in financing and the legal framework. Winter-ready materials, innovative technology, and flexible maintenance result in higher initial investments but pay off through lower ongoing costs and a higher quality of use. Funding programs and sustainable procurement concepts—such as those being piloted in Munich or Basel—can provide important impetus here.
Another problem area is coordination between planning, construction, and operation. Anyone seeking winter-ready design must involve all stakeholders early on and clearly define the interfaces between planning, execution, and maintenance. Only in this way can a consistent, robust concept be achieved—one that also stands up to the practical test in February.
Conclusion: Winter as a Test of a City’s Resilience
Winter is more than just a break between two summers. It is the stage on which the resilience, quality, and sustainability of climate-adapted urban and open-space design must prove themselves. Planning that is limited to heat protection and evaporative cooling remains incomplete. Only when spaces, materials, vegetation, and land-use concepts can also withstand winter conditions will a truly sustainable, year-round attractive urban landscape emerge.
This means that winter readiness is not a byproduct, but an integral part of good planning. It requires technical and design ingenuity, interdisciplinary collaboration, the courage to innovate, and open communication with all stakeholders. Cities that view winter as both a test and a source of inspiration create open spaces that remain inviting, safe, and conducive to social interaction even in the face of snow, ice, and darkness.
Those who invest now in winter-ready, climate-adapted design are not only preparing for the challenges of climate change but are also setting standards for sustainable urban quality. Winter is not an enemy, but a creative driver for robust, flexible, and vibrant urban spaces—and the best opportunity to put one’s own planning principles to the test.
