ECODEM studied the goals, ownership structure, and internal management of the building guild movement, a large network of interconnected construction companies owned and governed democratically by trade unions and their members. For this purpose, ECODEM analyzed a wide range of primary sources, including business reports, company agreements, contracts, debates in parliament, unpublished correspondences, personal papers, and numerous books, pamphlets, and articles that appeared in the socialist and trade union press of early interwar Britain and Weimar Germany. ECODEM thus presented the building guilds as a vivid illustration of the twofold strategy by which British and German socialist, trade union functionaries, and organized workers believed work could be made more democratic, namely by making sure, on the one side, that consumers were provided with decent and affordable housing while guaranteeing, on the other hand, that employees participate in making the decisions that directly affect their immediate work realities.
