Major-General George R Pearkes Building, Government office building in downtown Ottawa, Canada
The Major-General George R Pearkes Building consists of north and south towers housing the National Defence Headquarters at 101 Colonel By Drive.
The building, completed in 1974, was initially planned for the Department of Transport but became the Defense Headquarters when LeBreton Flats plans changed.
The structure represents Modern Brutalist architecture designed by John C Parkin, Searle, Wilby, and Rowland, marking Canadian institutional design of the 1970s.
Security protocols require visitor identification checks, and the building connects to public transportation networks throughout the National Capital Region.
The building features modular office furnishings manufactured in Canadian prisons during its 1990s renovation phase.
