The A.H. Hammond Organ Reed Factory is a nineteenth-century factory building that was constructed over a period of approximately 20 years. The earliest portion of the building is a wood-framed structure built in 1868. At least five major additions to the original building increased the size to a total of approximately 61,900 square feet on four floors. The building had been vacant for approximately 15 years before being purchased in 2006 by Worcester Common Ground, a non-profit, affordable housing developer. The demolition of one building and Rehabilitation of the others has resulted in 46 units of affordable rental housing, the first all affordable development in the Commonwealth.
