“The look on a client’s face when they step into their new home?
That’s why I still love this work.”

– Brett Irish

Brett Irish, Owner

I consider myself a facilitator more than anything. My goal is simple: to help our clients feel confident and satisfied with their build—ideally, even ecstatic.

Clients often ask for my input throughout the process. I’m always happy to share a builder’s perspective to help guide decisions and simplify next steps.

Of course, I’m just one part of a much larger team. We’ve built a crew of highly skilled tradesmen—each an expert in their craft—who treat every project with care and creativity. That’s how we’re able to build truly unique, custom-built homes that reflect your style and goals.

My passion for building started over 30 years ago on a dairy farm—fixing fences and building barns, sheds, and feed pins. That early experience gave me a hands-on understanding of hard work, precision, and pride. And today, nothing compares to the satisfaction of handing a client the keys to a finished home, knowing we built it right.
