In Vienna’s 9th district Julius-Tandler-Platz and Nordbergstraße were redesigned as an attractive, climate-resilient public space in front of Franz-Josef railway station. The square and the streetscape function both as a vibrant district centre and as an important transport hub. The project organizes a wide range of uses within a clear and coherent spatial framework.
Across approximately 8,000 m² clearly defined circulation routes, shaded places to pause, and generous green spaces are created. The design responds to the square’s constant movement and social interaction by establishing a legible spatial order that supports orientation, accessibility, and everyday use.

A triangular paving stone creates a distinctive surface. Two variations in the paving pattern differentiate main circulation routes from areas for lingering, guiding movement intuitively across the square. The interplay of form, colour, and material enhances spatial legibility and makes the public space easy to read and navigate.

Julius-Tandler-Platz brings together a wide variety of functions, including the railway station forecourt, tram stops, market stalls, outdoor dining areas, kiosks, and temporary events. Generous open areas allow these uses to coexist while improving the overall quality of stay. Nordbergstraße is redesigned as a shared space, creating a traffic-calmed urban environment with greater comfort for pedestrians and cyclists.

The design gives the area a clear and recognizable identity. Distinctive paving patterns, water features, and a carefully balanced mix of existing and new trees shape its character. A variety of seating options — including benches with armrests and backrests, as well as chairs and stools — offers places to sit, meet, rest, and observe urban life. Warm tones of colour in the paving and furniture, together with carefully composed planting, create a consistent atmosphere across the entire area.

Climate resilience is a central element of the design. A total of 70 trees, including 46 newly planted climate-resilient trees, provide shade and help reduce heat stress. Planting areas with grasses and perennials are increased and sealed surfaces reduced, expanding the amount of permeable green space.
A variety of water features provide cooling and invite play and interaction. Temporary pergolas offer immediate shade and can be removed once the trees have matured. Rainwater is managed according to the sponge city principle: collected runoff and reused water are used to irrigate the trees, support planting, and improve the microclimate.
