Union Mill and Artifact Coffee

Built as America's leading canvas factory in 1866, Union Mill commands a corner of Baltimore's Hampden/Woodberry neighborhood, where it has evolved into an effective mixed-use development. Originally constructed in 1866 and expanded in 1872, this landmark structure shifted from its industrial roots as the country's premier cotton duck producer to become an active residential and commercial community. The renovated complex includes 54 apartments designed for educators new to Baltimore, 25,000 square feet of office space dedicated to non-profit organizations, and Artifact Coffee, a gathering space housed in the building's former boiler house.

Design Resolution

Moseley's design team preserved the building's historic character while incorporating current amenities and sustainable features. A distinctive element emerged from the narrow space between the Boiler House and residential wing—converted into the main residential entrance through considered use of storefront glazing. This design creates visual connections to the courtyard while joining the building's distinct components.

Artifact Coffee: A Historic Boiler House Renewed

Within Union Mill's former boiler house, Artifact Coffee occupies 2,000 square feet of distinctive space. The design highlights original architectural elements, including exposed stone walls and an overhead framework of timber decking, beams, and trusses. Stained concrete floors blend with sections of distressed hardwood, adding texture and warmth. The layout maximizes seating capacity through communal tables and wall-mounted workspaces, creating an atmosphere suited to both social gatherings and individual work.

Industrial Heritage

Listed on the National Register of Historic Places, Union Mill honors its manufacturing legacy through specific design choices. Original architectural elements, including plaster walls, wood wainscot, and decorative cast iron columns, remain exposed throughout the building. Acknowledging the mill's history as a canvas producer, the design incorporates canvas art pieces and guardrails, integrating the building's industrial past into its current identity.

Environmental Excellence

Environmental responsibility guides Union Mill's redevelopment. The project achieved Baltimore City Green Building Standard 3-star Certification, equivalent to LEED-NC Gold. This recognition results from multiple improvements, including an exceptionally efficient mechanical system, enhanced building envelope performance, and practical location as a transit-oriented development. The formerly barren central courtyard has become a green half-acre urban oasis, offering residents and tenants a shared outdoor space.

Community Connection

Union Mill demonstrates effective urban development by building connections within and beyond its walls. The building's location provides convenient access to essential amenities, from grocery stores and pharmacies to restaurants and banking services. As a transit-oriented development, the site links to multiple transportation options, including bus lines and Light Rail service. The building's shared spaces—including conference rooms for office tenants and a dedicated copy center for teachers—support interaction and resource sharing among occupants.

Adaptive Reuse Achievement

Union Mill illustrates how historic structures can serve current community needs. The development has strengthened neighborhood stability while supporting Baltimore's educational and non-profit sectors. Through considered design and programming, this former industrial complex now houses a collaborative environment where educators and non-profit organizations work, live, and contribute together in a space that respects its past while meeting present-day needs.
