Lars Petterson-Adolph Carlson Three-Decker

The Lars Petterson-Adolph Carlson Three-Decker, built around 1918 in Worcester, Massachusetts, is a notable example of Colonial Revival architecture. This historic triple decker house features an asymmetrical facade with a unique combination of porches and a polygonal window bay. Originally constructed by local builder Lars Petterson, it reflects the development of the Greendale neighborhood as a streetcar suburb, primarily housing Swedish immigrants in its early years. The house was added to the National Register of Historic Places in 1990, making it a significant site for both tourists and researchers interested in early 20th-century residential architecture and immigrant history.
