A groundbreaking sports facility in Frauenfeld, Switzerland, has introduced an innovative approach to sustainable construction through its unique vertical timber design. The twin sports halls, designed by architectural studio kit, showcase an advanced timber construction system that prioritizes spatial efficiency, resource conservation, and environmental sustainability while maximizing functionality within a limited footprint.

The project stands out for its compact, vertically organized layout that enables both sports halls to operate efficiently within a constrained area, significantly reducing land use requirements while maintaining full functional capacity. This vertical stacking approach represents a creative solution to urban space limitations and demonstrates how thoughtful design can address contemporary challenges in public facility development.

A revolutionary aspect of the construction is Switzerland's first implementation of a timber-concrete composite ceiling system in a sports facility. This hybrid engineering approach offers a substantially lighter and more resource-efficient alternative to traditional reinforced concrete systems, marking a significant advancement in sustainable building technology for large-scale public facilities.

The project's commitment to sustainability extends to its material sourcing strategy, with extensive use of regionally sourced beetle wood harvested from the public client's own state forest. Of the total 603 cubic meters of timber utilized in construction, an impressive 565 cubic meters were obtained locally. This approach dramatically minimizes transportation distances, reduces carbon emissions, and actively supports regional forestry management practices. Remarkably, the volume of timber used in the entire project regenerates naturally in Swiss forests within approximately 30 minutes, highlighting the exceptional renewable capacity of this resource.

Architecturally, the building boldly expresses its construction methodology through clearly articulated timber frameworks that create a distinctive visual identity. The structural rhythm becomes a prominent design element visible on the exterior, complemented by continuous ribbon windows that emphasize horizontal proportions while maximizing natural daylight access throughout the interior spaces. Inside the facility, exposed spruce timber surfaces contribute to creating a warm, balanced interior atmosphere while helping maintain a stable indoor climate for athletic activities.

The project incorporates a forward-thinking circular construction strategy, with modular components designed for eventual dismantling and reuse. This approach significantly extends material life cycles and reduces long-term waste, establishing a model for responsible construction practices in public architecture. The modular design philosophy ensures that materials can find new life in future construction projects rather than ending up in landfills.

Through its sophisticated integration of locally sourced materials, innovative modular planning, and cutting-edge hybrid timber engineering techniques, the Sports Halls BZT Frauenfeld establishes a compelling reference model for resource-efficient and sustainable public architecture throughout Switzerland and beyond. The project demonstrates that environmental responsibility and functional excellence can work hand in hand to create exceptional public facilities.
