Irvine, Ayrshire, Scotland. Changes 1 (Old Irvine)

The video starts off with a red brick building at the start of Quarry Road, a builder's yard which was previously known as "The Grain Store". I don't know anything about this building in its previous life as a grain store, but was demolished in 1999 and is now the site of Kwik-Fit.
Conway's old premises were demolished and rebuilt somewhere in the region of 2003.
Cochrane the Ironmonger's old premises were demolished in early 1987 to make way for the new Safeway supermarket. It was rebranded "Morrisons" and shut down and demolished in 2006. Aldi and the surrounding retail park now sit where it was.
Thornhouse Court is a new development on Thornhouse Avenue. It sits where two large gasometers used to sit, supplying gas to the town. The site lay empty for many years before the new houses were built on their old site.
