Although originally intended to be an office, the building housed the National Gallery of Canada collection, before finally being converted into federal office space. The building was raised off of Elgin Street on a plinth, with the entry recessed behind granite-clad columns. The facade was clad with red granite framed between vertical concrete strips that ran the height of the building.

The Lorne Building was demolished in 2011 and its replacement, the James M. Flaherty Building, finished construction in 2014. Although the new building is much larger than the Lorne Building, it does manage to maintain a similar street presence on Elgin Street.
