I live in a suburb of Houston- our HOA only allows 4 garage doors and it had to look like it was originally built that way. It started as a 3 car garage on a pie shaped lot which gave us the opportunity to expand.
Originally the doors on the side were to a carport but it has since been enclosed. Now it has sliding barn doors on the side and a large swing out door in the back. The roll up doors were all for air flow because it gets so hot and humid here.
Here is a pic of the house and garage together:
