links The development of Birmingham by Jon Bounds • 23 September 2009 • 2 Comments Pretty much an 1918 version of the Big CIty Plan — including ideas for improving New Street station. [link]
Great find! I once dug out (from Birmingham City University library) a 1950s version of the Big city plan.
This included the first proposal for a civic centre on Broad Street, of which Baskerville House and the Hall of Memory were eventually, some recastings later, the only completed parts.
