Ottenbach school pavilion

The municipality of Ottenbach opted for a consistently sustainable modular timber construction method for the new building. The design by Bauart Architekten und Planer AG demonstrates that prefabricated and systematically planned construction concepts can not only be functional and flexible, but also impressive in terms of design and ecology. DM Bau AG was responsible as the general contractor and producer of the high-quality timber modules.

The pavilion was developed as an extension for the school and combines a clearly structured modular design with the use of sustainable materials. The modules were precisely prefabricated in the company's own factory and then assembled in Ottenbach in Knonauer Amt within a few days - a process that significantly reduced the construction time, noise emissions and environmental impact on site.

The building acts as a connecting element between the historic and new school buildings and blends harmoniously into the existing structure with its restrained, single-storey form. Unlike many comparable modular school buildings, the pavilion features a wraparound veranda with a generous canopy, which not only creates a pleasant atmosphere, but also allows for a façade made of painted three-layer panels and low window parapets. Vertically arranged climate convectors break through the otherwise typical grid of modular buildings and also give the building an independent architectural identity on the inside.

Sustainability as a design principle

It was important to the client to create a sustainable building. The cold roof in element construction ensures efficient insulation, weather resistance and a modern appearance. A large-scale photovoltaic system was installed for the energy supply. This produces significantly more electricity than the building itself requires and thus contributes to supplying the other school buildings. In addition, an efficient building technology concept with a heat pump and geothermal probe was installed, which both heats and cools the building.

Pleasant learning environment

The built-in composite ventilation system ensures a continuous exchange of air and contributes significantly to a healthy indoor climate. The natural timber construction ensures a pleasant, warm feeling inside. A large psychomotor room offers a wide range of opportunities for movement, play and encouragement for the children. In addition to high efficiency, the focus of the planning was also on flexibility. The modular design allows the building to be easily extended in the future.

Modular construction with exemplary character

Stefan Fuchs, of Bauart Architekten und Planer AG, emphasizes the exemplary nature of modular timber construction: "With its clear structure, high architectural quality and forward-looking energy concept, the Ottenbach pavilion shows that modular school buildings can be more than just functional stopgap solutions. It is an inspiring example of how economic, ecological and educational aspects can be harmonized - and a strong argument for the potential of modular timber construction."
