Urban Development in Karlsruhe: Focus on Hohenwettersbach and Stephanienstraße

Urban Development in Karlsruhe: From Urban Gardens to Construction Projects

The city of Karlsruhe has positioned itself in recent years as a pioneer in sustainable urban development. In February 2026, this dynamic continued – especially in Hohenwettersbach, where a new usage concept for the Lustgarten and an urban forest garden are planned, and along the Stephanienstraße, where the expansion of buildings is being discussed. These initiatives demonstrate how the city is seeking a balance between green space, living space, and social engagement.

Design of the Lustgarten and Development of an Urban Forest Garden

In the local council of Hohenwettersbach, the focus was on the future of the Lustgarten and the adjacent areas. A central project was the development of a design and use concept for the Lustgarten, complemented by the designation of a plot for a community and participatory garden.

Areas 1, 2, and 3 are to be redesigned into an urban forest garden, although sub-areas 1A, 1B, and 1C are unsuitable for the cultivation of food plants due to exceeded precautionary values (e.g., "Benzo(a)pyrene"). Nevertheless, the redesign of these areas as green space is feasible.

With a minimum area of 5,000 square meters, the forest garden will not only create a green lung for the region but also provide space for social and educational activities. The local council unanimously approved the change in land use and supported the designation of areas 1, 2, and 3.

Expansion on the Stephanienstraße: Urban Planning in a Tension Field

Another current project discussed in February is the expansion of the buildings at Stephanienstraße 30–32. The Design Advisory Board met on February 27, 2026, and addressed the question of how this measure fits into the overall urban image.

This expansion could on the one hand help to ease the housing market, but on the other hand also raise questions about accessibility, architecture, and social interaction. The Design Advisory Board plays a crucial role here in maintaining the balance between urban planning needs and cultural heritage.

Background: Politics and Processes in Hohenwettersbach

The political landscape in Hohenwettersbach is characterized by a colorful mix of parties, including the SPD, CDU, Greens, and FWH/FDP. The current composition of the local council has changed due to recent shifts: Julia Schulze Steinen, Dr. Elke Winkler, and Julia Wohlwender have resigned from their posts. New impulses are coming from Elke Ernemann (SPD), Detlef Kamlah (Greens), and others.

Transparency and public participation play a central role – a site visit of the areas took place already on January 10, 2025. In addition, agendas, documents, and meeting compositions are publicly accessible, which promotes civic participation.

Outlook: Green Space, Living Space, and Future Readiness

The developments in February 2026 show how Karlsruhe is advancing its forward-looking urban policy. The creation of urban green spaces such as the forest garden in Hohenwettersbach is a step toward a sustainable, livable city. At the same time, the expansion on the Stephanienstraße remains a symbol of the challenges that come with the housing market.

In the coming months, it will be interesting to observe how these projects are implemented and what role citizens play. The next meetings of the local council and the Design Advisory Board – among others on June 26 and October 9, 2026 – offer further opportunities to actively shape urban development.
