The present barracks complex was largely built in 1937–1939 to designs by William Alexander Ross.

[5] A monument outside the barracks on Redford Road commemorates the insurgent covenanters of the Pentland Rising who were defeated at the Battle of Rullion Green in 1666.

The monument was erected in 1884 by R A Macfie of Dreghorn House, and incorporates columns taken from the 18th-century Edinburgh Royal Infirmary, designed by William Adam and demolished the previous year.

As part of the Future Force 2020 budgetary announcement in July 2011, RAF Kirknewton was to have been developed into a major Army base to host a Multi-Role Brigade[7] and Dreghorn Barracks was earmarked for disposal.

Dreghorn Barracks had 670 UK Armed Forces Service personnel based there at 1 January 2024.
