Urban Development in Siegen: The Masterplan for Inner Development and the Building Plan for Eiserfeld Station

Siegen's Path to the Future: Urban Development and Inner Development

In March 2026, the Committee for Construction and Urban Development in Siegen made important decisions that will shape the urban development of the coming years. The focus was on inner development and the concrete implementation of building plan 463 "Bahnhof Eiserfeld". Both projects are part of a broader strategy aiming at sustainability, social mixing, and a compact urban structure.

The Masterplan for Inner Development: Foundation for a Vibrant City

The approved Masterplan for Inner Development is an urban development concept that will serve as a basis for future building plans and urban development contracts. It was developed in collaboration with the renowned planning firm AS+P (Albert Speer & Partner) and various stakeholders.

Goals and Content

The Masterplan includes a Potential Atlas for Inner Development, mapping vacant lots, underutilized plots, and conversion areas. The goal is to create a compact city structure to promote short distances, sustainable mobility, and a vibrant urban society. Key areas have been identified and equipped with design and usage concepts.

Sustainability and Social Mixing

The plan is embedded in the Sustainability Strategy NRW 2020 and pursues goals such as resource conservation, compaction of the city, and social mixing. It lays the groundwork for urban development that is not only ecological but also socially acceptable.

Building Plan 463 "Bahnhof Eiserfeld": Urban New Construction with a Mobility Focus

The building plan 463 for the area of the Eiserfeld Station is a central project in urban upgrading. The planning area southwest of the Siegtalbrücke bridge will be developed, with an urban zone (MU) designated. The total area is 2.08 hectares.

Planning Priorities

• Densification: The former freight station site will be developed to optimally utilize the existing open space.
• Mobility Hub: The station will be expanded as a central transport hub, with a focus on public transport, cycling, and electric mobility.
• Noise Protection: Due to high noise levels from rail and road traffic, passive noise protection measures are required.
• Legacy Sites: Although the site is considered a legacy site, no planning-relevant effects have been identified.

Funding and Support

The expansion of the station is supported by the funding program "Zukunftsbahnhof" (Future Station) of the German Railway. In addition, the project is part of Siegen's Climate Protection Concept, which aims to strengthen public transport and promote the expansion of electric infrastructure.

School Construction and Education: Renovation of the Realschule Am Oberen Schloss

Another important project in municipal construction planning is the renovation and expansion of the Realschule Am Oberen Schloss (Secondary School at the Upper Castle). With a budget of approximately 30 million euros, the school will be expanded to a three-track full-day school by 2033.

Renovation Highlights

• Energy Renovation: Insulation, window and heating replacement.
• Inclusive Orientation: 45 students in integrated learning.
• MINT Focus: Emphasis on Mathematics, Informatics, Natural Sciences, and Technology.
• Temporary Solution: Use of containers during the construction phase.

Funding comes from municipal budget funds, demonstrating how strongly the city connects education and infrastructure.

Outlook: A City in Transition

The decisions of March 2026 mark a milestone in the development of Siegen. With the Masterplan for Inner Development and the building plan 463, the city is not only developing spatially but also socially and ecologically sustainably. The combination of housing promotion, mobility development, school construction, and noise protection shows a holistic understanding of urban challenges.

In the coming years, it will be crucial to implement these plans transparently and in a citizen-friendly manner. Only then can Siegen become a compact, vibrant, and sustainable city for the future.
