Colonial Hall, also known as the Aldrich House for its association with the house's first owners and occupants, local medical and civil leaders Dr. Alanson and Dr. Flora Aldrich, is a two-story wooden building built in 1904 in a combination of Colonial Revival and Greek Revival styles by local renowned architect Fredrick Marsh.

The Aldrich House was purchased by the Anoka Lodge in 1921, and in 1922, construction began on the present two-story redbrick Masonic temple, which is located behind but to the north of the Colonial Hall.

In the 1980s, the Anoka County Historical Society's offices and library were housed in Colonial Hall.

[4] In December 2012 the decision was made to sell Colonial Hall to a private party for restoration.

[citation needed] In 2016, Colonial Hall is occupied by a tenant, The Big White House, an antiques store.
