this facade along James Street reveals a bit more detail: F.W. BROWN ARCHITECT No. 14 N. P ST.
Assuming this refers to Frederick Brown, his best known local work was the wooden lakehouse which predates the current one in Washington Park. 14 North Pearl Street no longer exists, but would've been near present Ten Eyck Plaza.
The cast iron facade has been painted since the last time I blogged about this building, but it is otherwise in a sad state.
