On Barbicantalk on this link is an excellent article by the user “Socktoy” which describes the various Barbican committees and how the Barbican is governed. Socktoy’s article includes the diagram reproduced below, which gives you an idea how committees are related, and is worthy of study if you want to get anything done. The solid black arrows on this chart mean “give instructions to” (more or less). So the BEO get their instructions from the Local Authority hierarchy (Housing Services) and from the Barbican Residential Committee (BRC). Note that the BRC is in pink. It consists of elected councilmen, some of whom are residents, but by no means all. The committees in yellow and blue are composed of residents. The committees in pink are composed of employees and elected members (councilmen) of the City of London.
