Heritage & Vision

Where History Meets Home

Tri Century Mill stands as a testament to the enduring beauty of heritage architecture and the vision of thoughtful restoration. Located on Mill Street in Carleton Place, Ontario, our building has witnessed three centuries of change while maintaining its timeless character—a charming small-town treasure just a short drive from Ottawa.

Today, the restored mill offers two unique experiences: boutique hotel suites for visitors seeking a memorable riverside stay, and elegant residences for those who want to call this historic landmark home. Every unit features brand new kitchens and bathrooms, with windows crafted to match the original heritage look.

Every corner of Tri Century Mill tells a story—from the original limestone walls to the massive timber beams, from the industrial-era brick additions to the modern amenities seamlessly integrated throughout. We invite you to become part of this continuing story.
