⛳ We're putting our design skills to the test!

Join us at Downtown Sioux Falls Open Streets today from 5:00–8:00 PM, where Main Avenue will be transformed into a one-of-a-kind mini golf course created by local businesses, organizations, and creative teams. Our Koch Hazard team has designed and built a custom hole, and we can't wait for you to try it out.

Bring the family, challenge your friends, and spend the evening enjoying mini golf, food, entertainment, and everything that makes Downtown Sioux Falls such a great place to gather. Stop by our hole, say hello, and see if you have what it takes to score a hole-in-one!

We hope to see you there!

Natural light changes more than just a room, it changes the experience of moving through a space.

Areas like stairwells and entries are often treated as purely functional, but they have the potential to become some of the most impactful moments in a project. By intentionally bringing daylight into these transitional spaces, we create environments that feel open, connected, and inviting from the moment you arrive.

The interplay of light, shadow, material, and structure adds depth throughout the day, turning circulation spaces into part of the architectural story instead of an afterthought.

Thoughtful design considers every step of the experience.

🌍 Earth Day is a reminder that great design can give new life - not just to spaces, but to entire communities. At Koch Hazard Architects, sustainability often begins with reimagining what already exists.

As the first LEED Platinum building in South Dakota, the Museum of Visual Materials (now Mosaic Arts and Events) is a powerful example. By transforming a former industrial building into a vibrant community arts space, the project preserves embodied energy while creating something entirely new and inspiring.

This kind of work reflects how we approach sustainability every day:
• Reusing structures to reduce environmental impact and construction waste
• Designing with natural light and openness to enhance experience and efficiency
• Creating spaces that bring people together and remain relevant for years to come

This Earth Day, we celebrate the power of adaptive reuse and thoughtful design to honor the past while building a more sustainable future. Because sometimes the most sustainable building is the one that’s already standing, just waiting to be reimagined.
