Modelled in Blender 2.59 and rendered with LuxRender. Tutorial on blenderguru.com (sorry cgcookie, but to my knowlege you didn't have an interior model+render tut.)
NOTE: This was modelled based on a background image of a real kitchen, which can be found at http://www.blenderguru.com/wp-content/uploads/2010/07/magazine.jpg
This is probably my best work yet.
