We recently finished adding a garage to the side of our house. We used to have an M5 and an M6 and had to park them in the gravel driveway next to it.
Here are some before and after shots with then the new M3 in there now replacing the M6.
I need to get something for the walls as it's a little dull. Looking at the other garages in this thread has given me some ideas. Thanks all for sharing!
