New Wooden Interim Classroom Building at Dietrich-Bonhoeffer-Gymnasium
A Promising Solution for Urgent School Space Needs
Construction preparations for the school building at DBG
In the heart of Bergisch Gladbach, Germany, the Dietrich-Bonhoeffer-Gymnasium (DBG) is set to receive a new three-story interim classroom building, constructed entirely of wood. The project, which began on August 12, 2025, at the Jan Wellem sports club, is a collaborative effort between SBGL, the city administration, political decision-makers, and various involved parties.
Construction Details and Timeline
The modular wooden building will provide urgently needed school space for up to 15 years. The structure, featuring three stories and engineered wood materials such as cross-laminated timber (CLT) or glulam beams, is designed for speedy assembly and potential disassembly.
The project's ambitious construction schedule relies on serial modular construction, with the main building parts prefabricated and delivered to the site, allowing assembly in a few weeks. The total estimated project duration is approximately 5-8 months from planning to handover.
Environmental Impact and Sustainability
The use of wooden construction is not only visually appealing but also ensures a modern and timely construction process. Wood is a renewable resource, and timber construction stores carbon dioxide, reducing the building’s embodied carbon footprint. Additionally, the use of engineered wood makes efficient use of raw materials and allows for precision manufacturing with minimal waste.
The wooden building's excellent insulation properties reduce heating and cooling energy needs, while potential integration of energy-efficient HVAC and lighting systems further reduces operational emissions. Prefabrication leads to less construction site waste, and components can often be reused or recycled after the interim usage period.
A Collaborative Effort
SBGL, the managing company responsible for the construction, has expressed its gratitude to the Jan Wellem sports club, city administration, political decision-makers, and all involved parties for their constructive cooperation and trust in the timely implementation of the project. The city administration contacted the adjacent sports club to find a suitable site for the new building, and the project is seen as an important sign for the future of schools in Bergisch Gladbach, with local construction companies contributing significantly to its successful implementation.
Traffic Disruptions and Contact Information
Increased truck traffic and temporary traffic disruptions during delivery phases are anticipated. SBGL has asked for understanding in advance regarding the traffic disruptions. For inquiries, please contact Schulbau GmbH Managing Director Sebastian Rolko at 02202 / 9797920.
The interim classroom building at Dietrich-Bonhoeffer-Gymnasium (DBG) is expected to be ready for occupancy by the start of the new school year in summer 2026. With its quick assembly time, reduced soil impact, and minimal disturbance, the project is a promising example of sustainable and efficient construction solutions for educational institutions.
Education and self-development will greatly benefit from the addition of the new interim classroom building at Dietrich-Bonhoeffer-Gymnasium, as it will provide students with a more conducive learning environment. The sustainable construction of this modular wooden building, with its use of renewable resources and energy-efficient features, showcases the commitment to education and self-development in a socially and environmentally responsible manner.
