Google Building Maker was a web application that allowed users to build three-dimensional buildings for inclusion in Google Earth. Buildings were created using simple three-dimensional shapes combined with aerial photos. Google reviews new building submissions and includes them in Google Earth's three-dimensional buildings layer when they are of sufficient quality and a better model doesn't already exist. Building models could be exported for editing in SketchUp. There were at least 127 cities available.
On 13 March 2013 Google announced that the Building Maker application would be retired on 1 June 2013; the cancellation became effective on 4 June.
