In 1861, a group of builders found themselves locked out of their building sites due to a dispute about working hours. Their three-month ban led to the formation of The Edinburgh Co-operative Building Company Ltd (ECBC). This group comprised many different trades - stonemasons, plasterers, plumbers and others sympathetic to their aims. Central to its mission was a co-operative spirit that was reflected in its adoption of the beehive motif. The company's first site was at Glenogle Park, by the Water of Leith near Stockbridge, where the foundation stone was laid on 23 October 1861. The layout of 11 terraces took the Rosebank development as its prototype, and was mostly complete by 1872.
