Anyway, I must admit I find photos are ideal because it's nice to see the final product and then I can figure out how to get there. Usually I'll google a show and get photos from several versions of the same production to get a better understanding of what design elements are required, then make my own design. Unfortunately "Out On A Limb" is proving to be rather elusive.

 

This was based on your discription of what you needed.  That was the first time I had worked with sketchup, (which is not the easiest product to work with).  I do have a quick drawn sketch that had a lot of detail, i.e. porch lights, shrubbery, furniture, fencing, ect.  Unfortunately, I can't seem to upload my design to post here.

Basically what is posted is just giving you an idea, based on you limited description, to give you ideas on which way you can go. 

Did you need a garage door that had to open or not?  If so you may want to use more of a barn door idea instead of over head door which can be a huge expense to do.
