The origins of this tower came from a feasibility study commissioned in 1986 by Northern Ireland Railways. MAP Architects produced the document which proposed a reintroduction of the Great Northern Railway associated with a commercial development to finance it. In 1988 a development group called Glenbank Estates successfully obtained the development rights to the scheme after an open competition. The developer retained MAP Architects for the project in which a building was designed which provided three glass and stainless steel tower structures at varying heights.
