It is a large, square, two-story brick industrial building.

History
The Mill #2 Annex was built between 1940 and 1942, by the Bethlehem Steel Corporation.

It was originally designed and built as a surface preparation and finishing mill for the Alloy and Tool Steel Division at Bethlehem Steel's Lehigh Plant in Bethlehem.

The 4.5 acre Mill No. 2 Annex was added to the National Register of Historic Places in 2004.

The building has since been renovated and currently contains condominiums, two commercial properties, and a parking garage.
