61-89 Jessie Street, Sentinel Works

The Sentinel Works is a former factory building in Polmadie, Glasgow, Scotland.

In 1994, the Sentinel Works were added to the Buildings at Risk Register for Scotland.

Today it is the third oldest surviving reinforced concrete building in the United Kingdom.

The flat roof construction anticipates the daylight-flooded American-style production facilities that would later also appear in England.

The designer Archibald Leitch is responsible for planning and construction in collaboration with the Brand & Lithgow architectural firm.
