What is most amazing about this program is its simplicity of use. I've made a quick model to show you guys the potential.
I started with a photo from the reference section of this site. The photo is Norm27.jpg
First off Sketch-up offers you a means to match the perspective of a building by manipulating the vanishing points.

Once you have done that with a bit of care you can create a model of the house and project the image as textures.

Once you have made the model you can manipulate it in 3d

What is really amazing then is you can get it to give you real dimensions based on the model you have made. (you can use the man figure to adjust the scale or use its guides system to make distances absolute)

I think the potential for this program makes it worth exploring.
