Certain kinds of garage doors are more sophisticated than others. If your door swings into the interior, then you'll need to make sure you have clearance.
This is where roller garage doors excel
- they take up room around the ceiling, but don't swing in the same way. As such, you can keep things nearer to the front of the space. On top of that, they also tend to be more secure.
Windows also matter. For maximum space around the walls, skylights might be preferred to traditional windows - provided that the building allows for them.
