W. H. Hill Envelope Company Building, Worcester

The W. H. Hill Envelope Company Building is a significant historical structure constructed in 1890. Designed by architects Fuller and Delano, the building is a 4 1/2-story brick structure with a flat roof. Despite its relatively plain facade and minimal ornamentation, the building's historical and industrial importance stands out. It is listed on the U.S. National Register of Historic Places.

It originally housed the Hill Envelope Company, which traced its origins to Dr. Russell Hawes, inventor of the envelope folding machine in 1846. Wade H. Hill joined the business in 1866, eventually becoming the sole owner and renaming it W. H. Hill Co.

The Hill Envelope Company played a crucial role in the evolution of envelope manufacturing in Worcester. Initially located on Grafton Street, the company became a part of the U.S. Envelope Company through a series of mergers involving several local envelope manufacturers. This factory remained operational under the U.S. Envelope Company until the 1970s, marking an era of industrial prominence for the building.

Today, the W. H. Hill Envelope Company Building has been repurposed and revitalized as Canal Lofts, a modern apartment complex.
