About Unrau Building Supply

Rooted in Boissevain,
Built with Family Values

Over 30 years of trusted post-frame building expertise across Manitoba & Saskatchewan.

Unrau Building Supply is a family-owned and operated company with a simple philosophy: deliver durable buildings, honest service, and workmanship you can count on. Our deep roots in Manitoba mean we understand the local landscape and the hardworking people who live here. We specialize in high-quality post-frame buildings, utilizing superior materials to ensure your structure withstands the toughest prairie conditions.

Today, Dylan and Raylin, the son and daughter of Marvin, proudly continue the family legacy, bringing the same dedication to quality, service, and community that the business was built on.

What truly sets us apart is our neighborly approach. We aren't just building machine sheds and commercial shops; we are building long-term relationships based on transparency and integrity. When you partner with us, you are choosing a team that treats your project with the same care and attention as if it were our own.
