The 11-story, 180,000-sf Lafayette Building at 433-437 Chestnut Street was built in 1907. It is located across from the Liberty Bell at Independence Mall and has park area on two sides. The property is expandable by adding stories aggregating approximately 57,000 sf on top of the existing structure.

The 24-story, 152,000-sf Architects Building at 117 S. 17th Street was built in 1931 and is the current headquarters of the Philadelphia chapter of the American Institute of Architects. An AIA store occupies the ground floor. "The location, one block from Rittenhouse Square, ideally positions it for a condominium or luxury hotel conversion," says Joseph Morningstar, senior managing director in the New York office of HFF.

He and Andrew Scandalios, managing director in the same office, are heading the investment sales team. Citing a confidentiality agreement, both men declined to disclose any further details about the properties.
