School Construction and Sustainability – The Future of Educational Infrastructure in Kronshagen

School Construction as a Central Building Block for the Future

In February 2026, the city of Kronshagen set important course corrections for the expansion of its educational infrastructure. With the focus on the Gymnasium Kronshagen, sustainable construction methods, and innovative implementation models, the city aimed to ensure long-term planning stability and financial efficiency. The new construction of the Gymnasium is not only an educational policy project but also a central building block for the city's development.

Gymnasium Kronshagen – Choosing the Four-Stream New Construction Option

In October 2025, three renovation and three new construction options (three, four, and five streams) were presented and subjected to a comprehensive lifecycle cost analysis. The evaluation over a 25-year period clearly showed that the four-stream new construction option (36,221 m³) was more economical than all renovation options. The four-stream renovation option came to a total of 114.12 million euros, significantly exceeding the cost of the new construction option at 104.78 million euros.

This decision was confirmed by the Committee for Urban Development in March 2026. The new building is expected to be operational in Q1/2030. The shorter construction period (2–3 years) compared to renovation options is another advantage, making the long-term operation of the Gymnasium more predictable.

Sustainability and Digital Planning – A Central Approach

The city of Kronshagen is relying on sustainable and digital planning tools to ensure long-term benefits for the community and the environment. The integration of BIM (Building Information Modeling) is recommended for as-built documentation and for interfaces with the CAFM (Computer-Aided Facility Management) system. Additionally, the inclusion of lifecycle management (LCM) in the planning phase is a central component of the construction planning process.

Green Building certifications, Cradle to Cradle (C2C), and ESG-compliant planning are firmly anchored as core elements of the construction planning. These measures not only contribute to sustainable construction but also enhance the project's attractiveness to external financiers.

Implementation Models – TU, TÜ, and PPP Compared

The city has opted for the TU/TÜ (Turnkey/Total Contractor) model as the preferred option. This model offers a faster process, schedule certainty, and cost efficiency—advantages that are particularly valuable for public construction projects.

In contrast, PPP (Public-Private Partnerships) offer long-term cost stability but require a lengthy procurement process (10–14 months) and early legal support. Moreover, flexibility and architectural freedom are limited in such models. Therefore, the city has explicitly chosen the TU/TÜ model to ensure planning remains transparent and controllable.

Modular Construction – Opportunities and Challenges

Modular construction is another key focus of the planning process. Unlike conventional and serial construction, modular building is characterized by a high degree of prefabrication. The production of 3D room modules takes place in the factory, minimizing on-site assembly time and simplifying construction site organization.

Advantages include high cost certainty, controlled quality, and weather-independent construction work. However, there are also limitations: modules are constrained by transport capacities, and adjustments after contract signing are largely impossible. Nevertheless, modular construction will continue to play a central role, particularly in educational and social facilities.

Conclusion: Sustainable and Future-Oriented Urban Development

The decisions made in February 2026 mark a milestone in the urban development of Kronshagen. With a focus on sustainable construction, digital planning tools, and efficient implementation models, the city has clearly defined its direction. The new construction of the Gymnasium is not only a step toward better education but also a statement in favor of future-oriented urban planning.

The coming months will show how these decisions develop in practice. With the inclusion of participation events, detailed financial planning, and a clear goal definition, Kronshagen is well positioned to successfully implement the new construction in the coming years.
