Duane Morris is moving its downtown Miami office from the Southeast Financial Center to a smaller space at the nearby Citigroup Center, a relocation that reflects a national trend toward smaller law firm workspaces.

Duane Morris is moving in September when its long-term, $16.8 million lease of the 34th floor penthouse begins at 201 S. Biscayne Blvd., offering views of Biscayne Bay, Bayfront Park and downtown Miami.
