Yes Frank Lloyd Wright. One of my favourite American architects. I modelled this view of the Ennis House early 2009 and then submitted it for the CGArchitect 3d Awards the same year. I used only photo references and a roof plan I managed to find at the time - now there is lots of reference and street view on Google maps.
The Ennis House (1924) is an amazing example of one the first concrete houses built. It is now a California State Landmark. It was the last and most monumental of the L.A textile block homes Wright did. I'm a fan.
The first colour render is the render I submitted. I also made some different lighting scenarios and a B+W version for fun. Modelled in 3dsmax2008 and rendered with Mental Ray. All post work done in Photoshop.
