Charles Kirk (1791–1847) was a builder and architect who worked on many buildings in Sleaford and South Lincolnshire, England.

The Kirk family had long been connected with the building trade and Charles' father, William (1749-1823), was a builder and architect in Leicester.

The business continued to prosper and Kirk and Parry established a countrywide reputation for their railway buildings and church restorations.

This entry shows the great influence that Robert Smirke’s Gothic revival County Hall in Lincoln Castle had on Kirk.

The accounts at the back of the journal provide a record of the many surveying and building projects undertaken by Kirk over the period 1833-1848.
