103 Colmore Row formerly known as National Westminster House was a building on Colmore Row, Birmingham, England. The original building was designed by John Madin and was completed in October 1975 as offices and a banking hall for National Westminster Bank. After National Westminster Bank vacated the building it passed through several ownerships but failed to lease its offices. In 2008 a plan by then owners British Land to demolish the tower and replace with a taller modern equivalent was approved. This plan never progressed and the building passed to the developer Sterling Property Ventures, who successfully applied to have the building demolished and a new tower constructed in 2015. Demolition began in July 2015 and was completed in January 2017.
