It is significant for its restrained Chicago School design by major Minneapolis architect Harry Wild Jones, and as a leading example of the older warehouse/office buildings in Minneapolis–Saint Paul.

[3] It was originally built as a warehouse for Butler Brothers, a mail-order firm, on the land that formerly housed the Athletic Park baseball stadium.

[4] It had rather heavy construction in keeping with its function as a warehouse, featuring thick interior masonry walls with thin, recessed windows topped by corbelled parapets.

The interior is built with heavy timber posts and beams, cut from Douglas fir grown near Aitkin, Minnesota.

The atrium on western side was built with more of the heavy timber construction exposed, and more efficient mechanical systems were installed.
