Checking the history on that image it turns out to be from a 2009 interior design site in Germany. http://borkenhagen-interior.com/#/category/arbeitsplatz/ Don't know if that helps you or not. I suppose you can contact them.

It's pretty simple really.

Open Google

Click the word Images at the top

While having this page open select hold and drop this image (or any image) to the search line on the Google images line (the one with the camera).

Then just read through the results.
