Interior rendering of small (tiny) spaces.

When creating interior renderings for really small spaces, the geometry of the surrounding walls is very limiting in the way you can position the camera, especially if you do not want to use extreme fisheye camera settings. Is there a way to position the camera outside of the space, and have one or two of the walls of the space not blocking the camera sight into the space (i.e. not getting rendered), but still having these walls produce the correct effects on the rendering, with respect to lighting effects (think window in wall, light reflected by wall) and being visible in reflective surfaces (think mirrors) elsewhere in the space?

Suggestions appreciated, Marcel
