Guild Street drill hall, Aberdeen

The building was constructed as a private house in the early 19th century and converted into the headquarters of the 1st Aberdeen Rifle Volunteers in around 1860.^[1][2] This unit evolved to become the 4th (The City of Aberdeen) Battalion, the Gordon Highlanders in 1908.^[3] The battalion was mobilised at the drill hall in August 1914 before being deployed to the Western Front.^[4][5]

By 1920 the battalion had moved out to the Woolmanhill drill hall (since demolished)^[6] and building alterations were carried out to the Guild Street drill hall, to the designs of George Bennett Mitchell, to convert the building into offices for George Mellis and Sons, a retail chain.^[7][8] The building subsequently became offices of HM Revenue and Customs and is now known as "Customs House".^[9]
