My partner and I would like to build a one car garage, but we do not know where to begin. Where can I find garage plans, so that I might get some ideas? Any help would be appreciated. Thanks!

First, try using a searcyh engine (like Google) and type in the words 'garage plans'. You'll find plenty of ideas, but if you want plans, you'll have to pay for them.

Another place to try is your local big box home improvement center (the orange one and the other one). Go to the bookshelves and you'll find plenty of books available on garage design and ideas.
