A cultural gathering space built from regionally sourced structural round timber has received two of Canada’s highest architectural honours. The Muscowpetung Powwow Arbour in Saskatchewan combines low-carbon timber construction, regenerative landscape design and Indigenous knowledge. Designed by Oxbow Architecture in collaboration with Richard Kroeker, the project recently won both the 2026 Governor General’s Medal in Architecture and an Architizer A+ Award.

Located on Treaty 4 territory within the Muscowpetung Saulteaux Nation, the Arbour provides a dedicated space for cultural celebrations and community gatherings. The design emerged from close collaboration with community members, Elders and local knowledge keeper Jeff Cappo. Its circular form references traditional Saulteaux lodges and reflects the cultural significance of the circle.

Structural Round Timber Reduces Embodied Carbon

The project showcases the potential of structural round timber (SRT) as a low-carbon building material. The design team selected materials and construction methods using a whole life cycle assessment. Compared with a conventional steel structure, the timber design reduced embodied carbon emissions by 68%.

The team also chose round timber instead of engineered glulam wherever possible. This decision reduced embodied carbon by a further 20% per structural member. Round timber requires minimal processing and retains its natural fibre orientation. As a result, it lowers manufacturing impacts while shortening supply chains and reducing transport emissions.

A tripod column system allows the structure to use smaller-diameter trees efficiently. This approach avoids the need for larger harvested trees while maintaining structural stability.

The Arbour spans approximately 1,275 m² and accommodates up to 2,500 spectators and 1,000 dancers. Its lightweight circular roof appears to float above the surrounding prairie landscape.

Regenerative Design Extends Beyond the Building

The project combines architecture and landscape into a single regenerative system. The surrounding 6.2-hectare site is being converted from conventional agricultural land into native perennial prairie vegetation.

According to the design team, the restored landscape will sequester an estimated 12.3 tonnes of CO₂e each year. At the same time, ending intensive agricultural practices will avoid a further 10.5 tonnes of annual emissions. Together, these measures are expected to help the project achieve carbon neutrality by 2031.

The conical roof features a central oculus that admits daylight to the gathering space below. The opening also allows grasses beneath the structure to continue growing naturally. This passive design strategy eliminates the need for artificial lighting during daytime events while strengthening the connection between the building and its landscape.

Climate-Responsive Architecture Rooted in Culture

Unlike many public buildings, the Arbour does not rely on mechanical heating or cooling systems. Instead, it uses passive design strategies to provide comfort during the spring, summer and autumn months when cultural activities take place.

The project reflects the Saulteaux concept of Mino-pimatisiwin, meaning “live a good life”. It supports cultural continuity while addressing environmental challenges through local materials, local labour and ecological restoration.

By combining Indigenous knowledge with contemporary timber engineering, the Muscowpetung Powwow Arbour demonstrates how regenerative architecture can deliver measurable climate benefits while strengthening community identity and connection to place.
