Ashland Lodge No. 23 of Ancient Free and Accepted Masons is located on North Main Street in a row of buildings which formed the core of Ashland's early commercial district.

As originally constructed, it was a brick building of two stories in the Italianate style. Its design is attributed to L. S. P. Marsh, a local contractor. It had an arcaded ground story of seven bays. The second story segmental-arched openings were connected at the arch head by a distinctive serpentine belt course.

In 1909, the second story was enlarged for an assembly room. In 1928, a partial third story was added and the façade was remodeled in the Georgian style. In both 1909 and 1928, the changes were designed by the leading local architect, Frank C. Clark.
