Commercial Space

The Washington Street Mills is a vibrant community of businesses and artists. Together under one roof are offices, restaurants, manufacturers, retail stores, a range of service providers, nonprofits, and an artists’ colony, complete with gallery. In former years, these mills have been known as the Clarostat Building and One Washington Center. Today, the historic mills are once again alive with the sound of commerce—not the textile industry of old—but an exciting and diverse blend of creative and talented entrepreneurs. There is even an award winning restaurant run by a James Beard nominated chef. Visit the Washington Street Mills, and discover the goods and services available, incredible artwork, and the beauty of these restored buildings. This is a very exciting environment in which to work, to collaborate with other businesses, and location to explore.

From Our Residents & Tenants

“The Washington Street Mills is perfect for a startup or small business. The spaces are lovely and unique, and the mills are a wonderfully eclectic environment with their mix of artists, manufacturing, bakers and businesses of all types. It’s a true community, and lovely to be right on the river in a historic mill!”

Crystal K.

“Originally I rented from Chinburg Properties for the price. Over the last 8 years I have developed an appreciation for the diversity of the businesses and tenants located on the property. More often than not I find myself giving my clients tours and history lessons about the building on the walk to and from my office. I also promote the merits of many of the businesses here. I would urge any start-ups or smaller businesses to look at a Chinburg property before signing a lease elsewhere. ”

“The Washington Street Mill is a good place to operate a business. The management and staff are responsive and friendly, the building is well maintained, and the other tenants are pleasant to associate with.”
