Why it's listed
Located at 144-148 Main Street in downtown Worcester, this five-story brick building dates to 1885 and combines Victorian Gothic design with the offshoot style known as Panel Brick. The symmetrical facade has an arched entry at street level flanked by a storefront on each side. Upper floors hold eight evenly spaced windows per story, trimmed with rock-faced sandstone lintels and sills and separated by panels of decorative brickwork. A slight corbelled cornice supports a paneled parapet topped at the center by a decorative gable and date stone. Stephen Earle, one of the city's most prominent architects, designed it, and C.A. Vaughan built it for $30,000. It originally held two street-level stores and a boarding house above. The estate of George F. Armsby, a former secretary of the Munroe Organ Reed Company, apparently built it as an investment. It is regarded as one of the most ornate and well-preserved buildings of its period downtown.
Significance in brief: The nomination describes it as one of the most ornate and well-preserved examples of its period in downtown Worcester, combining Victorian Gothic design with Panel Brick architecture. It was designed by Stephen Earle, one of the city's most prominent architects, and built as an investment by the estate of George F. Armsby.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
