The Adams-Pickering Block is located in central Bangor, just south of West Market Square, at the northwest corner of Main and Middle Streets.

It is a four-story, Second Empire-style building, which is distinctive for its granite facade, cast iron trim, and mansard roof.

When built in 1871, its ground floor had mostly cast iron elements, but the storefronts have been modernized, and only fragments of the original trim remain.

[3] It was one of a number of high-profile commissions Orff executed in downtown Bangor in those years, of which this is a rare survivor of both the Great Fire of 1911 and urban renewal of the 1960s.

According to historian James Vickery he "was called the best businessman in Bangor by his contemporaries"[4] It was listed on the National Register of Historic Places on May 2, 1974.
